Density

Liquids

Introduction

You probably know that when solid objects are placed in liquid, they can sink or float. But did you know that liquids can also sink or float? In fact, it is possible to stack different layers of liquids on top of one another. The key is that all the different layers must have different densities. You can stack them by picking several liquids with a range of densities or by varying the density of one liquid by adding chemicals such as sugar or salt to it. If you choose colored liquids or add food coloring to each layer, you can even create a whole rainbow of colors in one single glass! Want to see for yourself? In this science activity you will stack several liquids—one by one—and create a colorful density column!

Background

Whether an object sinks or floats depends on its density compared with the density of the liquid into which it is dropped. All types of matter—solids as well as liquids—are made up of many different atoms. Depending on the mass of these atoms, their size and the way they are arranged, different substances will have different densities. The density is characteristic for each individual compound and defined as the mass of a compound divided by its volume. In other words, the more matter there is in a certain amount of volume, the denser a substance is. One cubic centimeter of rock, for example, is much heavier than a cubic centimeter of wood. This is because there is much more matter in the same volume of rock compared with the wood.

ADVERTISEMENT

Liquids can also have different densities. Freshwater, for example, has a density of about one gram per cubic centimeter at room temperature. Any compound—liquid or solid—that has a higher density than water will sink whereas substances with a lower density than that will float. You can test that for yourself by gathering several liquids that you have in your kitchen such as vegetable oil, corn syrup, dishwashing soap, water, rubbing alcohol and more. Which one of these do you think will sink or float in water? Find out in this activity!

Materials

Glass or cup

Water

Food coloring

Scissors

Rubber band (wide)

Small piece of wax

Popsicle stick

At least two small, clear jars or transparent mini cups (two ounces) with lids

Permanent marker

Masking tape

Three tablespoons

Dark corn syrup

Vegetable oil

Penny

Paper towels

Rubbing alcohol, dishwashing soap and other liquids (optional)

Sugar (optional)

Preparation

Gather all your materials at a workspace that can tolerate spills of all the liquids.

Fill a cup with tap water and add a couple of drops of food coloring to the water.

Ask an adult to help you cut and prepare small pieces (about 0.5 by 0.5 centimeter) of the rubber band, the popsicle stick and the wax.

Place the two empty jars in front of you (without the lids) and label them “1” and “2” with a piece of tape and the permanent marker.

Procedure

Take a clean tablespoon and pour two tablespoons of corn syrup in jar 1.

With the second tablespoon, carefully pour two tablespoons of colored water into jar 1 on top of the corn syrup. What happens to the water on top of the corn syrup? Does it mix or stay separate?

Use the third clean tablespoon to pour two tablespoons of vegetable oil in jar “1” on top of the colored water. Do you see mixing of the liquids? What happens to the oil? Does it float on top or sink to the bottom?

Now take empty jar 2 and add the same liquids—but in reverse order. Start by pouring in two tablespoons of vegetable oil.

One way to separate the different kinds of matter in a mixture is through


A. filteration
B. decomposition
C. electrolysis
D. chemical reactions

Answers

The answer is filtration (A).

Creating a mixture is a physical process; as such, the substances that make up a true mixture do not undergo any chemical reactions with one another. It follows, then, that to separate substances that are mixed together, the process to use would be physical, not chemical. Filtration fits that bill: Solutes that do not dissolve in the solvent can be trapped, for example, by a fine mesh whose openings are large enough for the solvent to pass through but too small for the undissolved solute(s) to do so.

Choices B, C, and D are all chemical processes.

Decomposition (B) is the breakdown of a substance into chemically distinct fragments. For example, hydrogen peroxide in a mixture (solution) with water decomposes in the presence of an appropriate catalyst—the products you are left with are water and oxygen gas, which bubbles out of the mixture. But you haven’t separated the hydrogen peroxide from the water—through decomposition, the hydrogen peroxide molecules are broken up and the atoms rearranged to form different molecules. There’s no hydrogen peroxide left to separate anymore. So, decomposition doesn’t separate different substances in a mixture—it transforms them.

Electrolysis (C) is a chemical process that uses an electric current to drive the movement of charged particles (electrons and ions) through a conductive medium. Suffice it to say that this will almost certainly change the chemistry of a mixture. For example, assume you’ve got a mixture of some inert, insoluble solute in water. If you run a very strong electric current through water, you’ll end up decomposing the water molecules themselves into oxygen and hydrogen gases. Again, you haven’t technically separated the solute from the mixture because separation implies that you have the separated substances still around. In this example, you’ve “separated” your solute by chemically transforming your solvent into two different gases; one part of your mixture no longer exists. (Side note: electrolysis of pure water takes quite a bit of energy; on the other hand, tap water, which contains dissolved electrolytes, can be readily decomposed via electrolysis using the current delivered by a standard alkaline battery.)

As a rule of thumb, the suffix (–lysis) usually indicates chemical decomposition, and the stem that precedes the suffix usually indicates what the decomposition process involves. Examples include electrolysis (as we just discussed), hydrolysis (breaking a chemical bond using water), glycolysis (the biochemical process of breaking down glucose into smaller molecules to harness the energy released), and radiolysis (splitting a bond within atoms comprising a molecule using ionizing radiation).

Finally, as should be clear by this point, chemical reactions are not the way to go about separating mixtures. Again, the chemical substances in a mixture retain their chemical identities. Separating the constituents of a mixture essentially entails isolating these substances. Filtration can and does isolate solutes from solvents without altering their chemical identities (assuming the filter itself is chemically inert). A chemical reaction changes a substances chemical identity, and so could not properly be regarded as a method of separation, and only separation.

One way to separate the different kinds of matter in a mixture is through filtration. The correct option is A.

What is filtration?

Filtration is a physical or mechanical process by which two or more substances are of different compositions. These substances can be solid, liquid, or gas.

There are three types of filtration. These are mechanical, chemical, and biological. The different types of filtration are based on a similar principle, which is a mixture of several types poured onto a filter membrane. A specific size of the pore is present in the filter membrane.

The other options are decomposition, which is a process of breaking down substances. Electrolysis is separating charged ions and chemical reactions to form compounds.

Thus, the correct option is A. filtration.

Explanation:

The elements are determined by the their symbol i.e. H = hydrogen.

The number of molecules is determined by the coefficient ( the number in front of everything, in this case 4).

The number of elements is determined by the coefficient and the subscripts. Multiply the coefficient by the subscript after each element. When there is no subscript, it is equal to 1.  4H₂ = 4x2 = 8;  4O = 4x1 = 4.

The number of atoms is all the individual elements added together. 8+4 = 12.

When the water and the mug are at the same temperature then thermal energy will no longer be transferred from the boiling water to the mug. Therefore, option (D) is correct.

What is thermal energy?

Thermal energy is generated in a substance when an increase in temperature causes atoms and molecules to move at a faster speed and result in the molecules colliding with each other. The energy generated from the temperature of the heated material is called thermal energy.

Thermal Energy or internal kinetic energy is because of the random motion of molecules in the system. The thermal energy of any system is directly proportional to its temperature.

The more the temperature of the system, the more the movement of molecules within a given system, and the more the thermal energy of the system.

The thermal energy will be transferred from the boiling water to the mug when the water is hotter than the mug. When both have the same temperature then the thermal energy is no longer being transferred from boiling water to a mug.

Answers

Answer:

0.127 N/m² or 0.127 Pa

Explanation:

From the question given above, the following data were obtained:

Radius (r) = 5 m

Force (F) = 40 N

Pressure (P) =.?

Next, we shall determine the Surface area of the sphere (i.e the balloon). This can be obtained as follow:

Surface area = 12.56 × r²

Radius (r) = 5 m

Surface area = 12.56 × 5²

Surface area = 12.56 × 25

Surface area = 314 m²

Finally, we shall determine the pressure as follow:

Force (F) = 40 N

Surface area = 314 m²

Pressure (P) =.?

Pressure = Force /Area

Pressure = 40/314

Pressure = 0.127 N/m² = 0.127 Pa

Therefore, the pressure inside the balloon is 0.127 N/m² or 0.127 Pa.

How many carbon atoms are there in 2.23 grams of propane (C3H8)?​

Answers

Answer:

Explanation:

Propane (C₃H₈) is a colorless alkane gas with three carbons and eight hydrogen atoms. In 2.23 grams of propane, there are 3.05 x 10²³ carbon atoms present.

What is the number of particles/atoms?

The number of atoms or the particles being the smallest units is estimated by the product of the number of moles and Avogadro's number.

The Avogadro's number (Na) is used to determine the number of particles that have been present in a mole of a substance. A mole of a substance is said to have 6.022 × 10²³ ions, atoms, electrons, molecules, etc.

Moles of propane are calculated as,

Moles = mass ÷ molar mass

= 2.23 ÷ 440.094

= 0.05057

Now, the number of particles is calculated as,

Number = moles × Avogadro's number

= 0.05057 × 6.022 × 10²³

= 3.05 x 10²³

Therefore, 3.05 x 10²³ carbon atoms are present in 2.23 grams of propane.
