BRAINLIEST TO FIRST RIGHT ANSWER

Students were investigating heat transfer by conduction and they set up the simple experiment you see here. They utilized three spoons made of different materials: the specific heat capacity of each material was recorded in the students' data table. Each spoon was placed in a pot of hot (90°C) water and a pat of butter was placed on the handle of each spoon. The butter melted first on the tin spoon and in about the same amount of time on the plastic and wood spoons. Based on the data table and the experimental results select ALL of the conclusions that are appropriate.

A) Conduction occurred more readily in the tin due to its lower specific heat
capacity

B) Heat transfer via conduction occurred from the hot water to the spoons
and then to the butter,

C) When in contact with hot water, there was no transfer of kinetic energy
through the wood or plastic

D) The atoms in the tin spoon vibrated and collided at a greater rate thon
those in the wood or plastic spoons

E) In all three cases energy s transferred from the faster moving hot water
molecules to the slower moving molecules in the spoon​

The different behavior of particles in solids and gases, including the intermolecular forces and kinetic energy, leads to solids filling only part of a closed jar while the same mass of a gas fills the whole jar. A solid fills only part of a closed jar, while the same mass of a gas fills the whole jar due to the differences in the behavior of particles in each state of matter.

1. Solid: In a solid, the particles are tightly packed and held in a fixed position. They have a definite shape and volume. The intermolecular forces between the particles are strong, preventing them from moving freely. As a result, solids occupy a specific amount of space within a container.

2. Gas: In a gas, the particles are spread out and move freely. They have no definite shape or volume. The intermolecular forces between the particles are weak, allowing them to move and fill the available space. As a result, gases can expand to fill the entire volume of a container.

When the same mass of a gas and a solid are placed in a closed jar, the gas particles have higher kinetic energy and are more mobile. They collide with each other and the walls of the container, exerting pressure and spreading out to occupy the entire space. Since the intermolecular forces are weak, the gas particles are not constrained by a fixed arrangement.

Nomenclature is the process of naming chemical compounds with different names so that they can be easily identified as separate chemicals. Inorganic compounds are compounds that do not deal with the formation of carbohydrates, or simply all other compounds that do not fit into the description of an organic compound.

Answer:

The lack of accuracy and underestimation of absorbance readings obtained from the colorimeter can be contributed to many experimental factors. One plausible error is from the imperfection of the absorber, in that it may not completely absorb the stray light passing by the perimeters of the photoresistor.

Explanation:

In practice there are other sources of error, such as environmental effects on photometer and sample, temperature, line voltage fluctuations, vibrations, contamination, or heating of the sample by the photometer. All these factors may impair the measured result, and ways and means are known to test and eliminate them.

The graph shows the change in temperature of a sample of water in a closed system as thermal energy is added over time. 150°C 100°C Temperature (°C) 50°C 0°C -50°C 10 20 30 40 Time (min) 50 60 during changes of state water particles maintain a constant speed. Therefore, option B is correct.

The term thermal energy is defined as the energy contained within a system that is responsible for its temperature.It is formed when the atoms and molecules in a substance vibrate faster due to a increase in temperature.

The examples of thermal energy sources are fossil fuels like natural gas, coal and oil, and solar heat, heat pump electric heat, and geothermal heat.

Thus, during changes of state water particles maintain a constant speed, option B is correct.

Both the elements combine together due to incomplete outermost shell.

Two atoms of element Q mixed with element E​ in order to achieve stability because both the elements have incomplete outermost shell which make them very reactive. In element E we can see that it has 7 electrons while on the other hand, element Q has 5 number of electrons.

For gaining stability, each element has to reach 8 electrons so that's why both the elements react with each other and get stability so we can conclude that both the elements combine together due to incomplete outermost shell.

Answer:

If the molecules have similar molar masses and similar types of intermolecular forces, look for the one that is the most polar or that has the most electronegative atoms or the most hydrogen bonding groups. That one will have the strongest IMF's overall.

Explanation:

An experiment that would show that intramolecular forces are stronger than intermolecular forces will be heating a block of ice in a sealed container then allowing it to change to steam.

Intramolecular forces are the forces of attraction that hold atoms together within a molecule. Intramolecular forces require a high amount of energy to splits atoms or molecules in a chemical bonding.

Intermolecular forces are weaker forces of attraction that occur between molecules. They require lesser energy to splits molecules compared to intramolecular forces.

An experiment that show that intramolecular forces are stronger than intermolecular forces will be heating a block of ice in a sealed container then allowing it to change to steam.

In the process, the energy required to change the state from ice to steam water is more than intermolecular forces.

Thus, we can conclude that this experiment shows that the intramolecular forces are stronger than the intermolecular forces.

La energía cinética está relacionada con la velocidad de las partículas.

Sabemos que la velocidad de las moléculas de gas depende de la temperatura del cuerpo. La temperatura de un cuerpo es una medida de la energía cinética promedio de las moléculas del cuerpo.

Debemos notar que cuanto mayor es la temperatura del cuerpo, mayor es la velocidad de sus moléculas. Por lo tanto, a una temperatura de 10,000,000 ° C, las moléculas en el núcleo del sol tienen una velocidad mayor que las moléculas en la superficie del sol.

Todas las moléculas, ya sea en el núcleo o en la superficie del sol, se mueven a mayor velocidad que las moléculas de la limonada a una temperatura mucho más baja. La energía cinética está relacionada con la velocidad de las partículas.

polymerization

Explanation:

Glucose is converted into starch by the process called polymerization. In polymerization, several simple and soluble molecules of glucose are put together to form a complex, insoluble molecule of starch.

Glucose is soluble , so it is converted to starch so that it can become insoluble and hence it cannot escape from cell , thus it can also be stored.

Answer:

Ok, so the process here is to convert the mass of H2 (hydrogen gas) to moles by dividing the mass by the molar mass of H2. Once you have the moles then you have to multiply by the STP (standard temperature and pressure) molar volume which should be 22.4.

Molar mass of H2 = (1.01)x2 = 2.02g/mol

19.3/2.02 = 9.55 moles

Now just multiply the moles by the molar volume

9.55 moles x 22.4 = 213.92 Litres of H2 are in 19.3g of H2

because it's just a physical change, the matter won't be changed.

Hope this might help you! I don't know if this is going to be right on everything, but it's a anwser

In a physical change, the makeup of matter is changed. This statement is false.

A physical change occurs when a substance experiences a change in its physical characteristics. A physical alteration may usually be reversed. No new material is produced with such a transformation.

As the substance's composition changes, a chemical reaction takes place. A chemical change happens when bonds are broken and new ones are created.

Physical change is a sort of change when the substance's chemical makeup does not change. Often, this type of alteration entails a change in the substance's size, form, and condition.

Thus, In a physical change, the makeup of matter is not changed because it's a physical change.
