Answer:
Because the particles are in motion, they will have kinetic energy. The particles will not all have the same energy, and the energy of the particles is constantly changing as they undergo changes in speed. Thus, for a given sample of matter, we can only talk about the average kinetic energy of the particles.
Explanation:
I hope this helps and pls mark me brainliest :)
We do know that if we "give" energy to a given object, the temperature of the object increases.
So there is a direct relationship between temperature and energy.
From this idea, we can conclude that:
"As we increase the energy, we also will see an increase in molecular motion."
We also do know that, as the temperature of an object increases, also does the kinetic energy of the particles that conform to the object (as the kinetic energy increases, the particles move more, this is why as we increase the temperature we usually see an increase in the volume of the object).
This increase in kinetic energy is related to the molecular motion (the movement of the electrons and nucleus o a molecule) as the kinetic energy of these parts increase, these move more.
So the relationship between molecular motion and energy is:
As we increase the energy, we also will see an increase in molecular motion.

Essential Question:
How does the transfer of thermal energy become minimized or maximized?
explain you hypothisith
Answer:
when it reduces heat.
Explanation:
Thermal energy is transferred to material,the motion of its particles speeds up and it's temperature differences.Insulating materials are bad conductors and so this reduces the heat loss by conduction.The material also prevents air circulating inside the cavity,therefore reducing heat loss by convection.Heat loss through the roof can be reduced by laying loft insulation.

A rock that falls off a cliff represents both potential and kinetic energy. Which statement best represents the energy transformation involved in this scenario? As the potential energy decreases, the kinetic energy decreases. As the potential energy decreases, the kinetic energy decreases. As the potential energy increases, the kinetic energy increases. As the potential energy increases, the kinetic energy increases. As the potential energy decreases, the kinetic energy increases. As the potential energy decreases, the kinetic energy increases. As the potential energy increases, the kinetic energy stays the same
Answer:
as the potential energy decrease the kinetic energy increases
Explanation:
at the cliff it possess maximum potential energy but as it falls it possess maximum Kinetic energy
When the rock is still stationary at a height, it possess all potential energy. As it begins to fall from the height, potential energy decreases and kinetic energy increases.
Energy transformations involve the change of energy from one form to another in accordance with the principle of energy conservation.
For a rock found at a height, all it has is potential energy. This potential energy decreases when the rock begins to fall and kinetic energy increases accordingly.
Hence, for a rock that falls off a cliff, as the potential energy increases, the kinetic energy increases.

Explanation:
the further down the group you go, the larger the radius becomes. its caused by the amount of electrons needed to equal out the charge of the nucleus
Atomic radius increases down the group in the periodic table and due to the increase in the number of shells.
Explanation:
The group in the periodic table is a vertical column running from top to bottom.There is a total of 18 groups in the modern periodic table.Elements in the same group have the same number of valence electrons and chemical and physical properties.When we move down in a group the atomic radii of the elements increases because the number shell increases which results in increase atomic radii of the elementsMetallic character increases on moving down Non-metallic character decreases on moving down Ionization energy decreases down the group as the atomic size increases the distance of valence electrons from the nucleus also increases which reduces the effective nuclear charge on the valence electrons.So, from this, we can conclude that atomic radius increases down a group in the periodic table and due to the increase in the number of shells.

The specific heat of water is 4.2j/g ºC how much heat is required to raise the temperature of 100 g of water by 5 ºC
Answer:
116,823 J
Explanation:
formula : q=m C delta T
q = heat = unknown
mass = 100 g
C = specific heat = 4.2 J/K*g
delta T = temperture in Kelvins: 5 + 273.15 = 278.15 K
q = (100 g) ( 4.2 J/K*g) (278.15 K) = 116,823 J
A cylinder of an ideal gas contains 1.2 moles of gas and occupies a volume of 5.0L. If 0.5 moles of a second gas are added to the cylinder, and the cylinder is allowed to expand until it reaches the same temperature and pressure as before, what is the final volume of gas, in liters, that occupies the cylinder?
Answer:
7.08 L
Explanation:
From the question given above, the following data were obtained:
Initial mole (n₁) = 1.2 moles
Initial volume (V₁) = 5 L
Final mole (n₂) = 1.2 + 0.5 = 1.7 moles
Final volume (V₂) =?
From ideal gas equation,
PV = nRT
Divide both by n
PV / n = RT
Divide both side by P
V / n = RT/P
RT/P => constant
Therefore,
V₁ / n₁ = V₂ / n₂
With the above formula i.e
V₁/n₁ = V₂/n₂
We can obtain the final volume of the gas as follow:
Initial mole (n₁) = 1.2 moles
Initial volume (V₁) = 5 L
Final mole (n₂) = 1.7 moles
Final volume (V₂) =?
V₁/n₁ = V₂/n₂
5 / 1.2 = V₂ / 1.7
Cross multiply
5 × 1.7 = 1.2 × V₂
8.5 = 1.2 × V₂
Divide both side by 1.2
V₂ = 8.5 / 1.2
V₂ = 7.08 L
Therefore, the final volume of the gas is 7.08 L

Which statement about the ocean is true?
1. No evaporation or precipitation in the water cycle occurs over the ocean.
2. Most evaporation and precipitation in the water cycle occur over the ocean.
3.All evaporation and precipitation in the water cycle occur over the ocean.
4.Evaporation, but not precipitation, in the water cycle occurs over the ocean.
Answer: The answer is probably B because most of the precipitation and evaporation in the water cycle happens over the oceans. Including, about 78 percent of the precipitation and 86 percent of evaporation.
The statement about the ocean is true is most evaporation and precipitation in the water cycle occur over the ocean. Therefore, option 2 is correct.
What is water cycle ?The continual movement of water on, above, and below the Earth's surface is referred to as the water cycle, also known as the hydrologic cycle or the hydrological cycle.
The water cycle is composed mostly of four processes: evaporation, convection, precipitation, and collection. When water in rivers, lakes, or the ocean is heated by the sun and turned into vapour or steam, this process is known as evaporation. The river, lake, or ocean releases water vapor or steam into the atmosphere.
The hydrologic cycle is crucial because it determines how water gets to people, plants, and other species. In addition to supplying water for people, animals, and plants, it also transports nutrients, diseases, and sediment into and out of aquatic habitats.
Thus, option 2 is correct.

For an experiment, Yolanda rubs a cloth against a balloon and places the balloon next to running water. What happens? The balloon breaks from the pressure of the water. The charged balloon repels the water. The uncharged water is attracted to the charged balloon. The water spills over the balloon, and the balloon gets wet.
Answer:
The uncharged water is attracted to the charged balloon.
Explanation:
Electrostatics is the study of charges at rest. Neutral bodies have equal and evenly distributed positive and negative charges. However, these neutral bodies can become either positively or negatively charged. These charges can be produced by either of friction, contact or electrostatic induction.
For example, when an ebonite rod is rubbed with fur, the ebonite rod acquires a charge by friction. The ebonite rod becomes negatively charged while the fur is left with positive charges.
Similarly, for the experiment performed by Yolanda, when she rubs a cloth against a balloon, the balloon becomes negatively charged . Water is neutral in that it is composed of equal positive and negative charged particles. When she brings the balloon near the water, the positive charged particles in the water will move the water towards the negatively charged balloon since positive and negative charges are attracted to each other.
