What happens to the thermal energy of a substance as its temperature increases?
When a sample of a substance absorbs thermal energy, its temperature rises.
What happens to the motion of molecules of matter when an object gains or loses thermal energy?
Increasing temperature means increased kinetic energy on the atomic or molecular level. Temperature of a given substance is the average kinetic energy of the particles of which that substance is composed.
Why does temperature stay the same during a phase change?
The temperature, in Physics, means the measure of Kinetic Energy in a substance. When a substance is either heated or cooled, Kinetic Energy is either being added to taken away from the substance. When the amount of KE in the substance changes, the temperature change. However, when the substance is changing its state, because all the KE change in the substance is being used up to change the state, the temperature will not change. When the substance is changing state, the KE can be measured by calculating the heat of fusion and heat of vaporization.
What happens to the temperature of a substance when you prevent gain or loss of thermal energy?
If you define "thermal energy" as heat, and the "substance" is not affected by any energy that increases or decreases its temperature, by definition, nothing will happen to its temperature. If the substance reacts to electromagnetism, light or other radiation, it may increase or decrease its temperature, depending on the nature of the substance and its reaction to those energies. Note: See Discussion question.
How does energy play a part in matter changing state?
Energy directly relates the the temperature of a substance. The more energy in is proportional to a higher temperature. The inverse is also true. When changing states you must use the formula Q=ML where Q is the energy in Jules, M is the mass in grams and L is the latent heat (fusion or vaporization) of the substance. This determines how much energy is needed to change state.
What happens to the temperature of substance while it is changing state?
It can lose or gain energy or it forms the attractions between particles.
What happens to temperature of a substance while it is changing state?
It can lose or gain energy or it forms the attractions between particles.

What happens to the temperatures of a substance while it is changing state?
It can lose or gain energy or it forms the attractions between particles.
When a substance changes state what happens to its thermal energy?
Changes the temperature of the substance
Thermal energy added to a substance that is not changing state causes the substances temperature to do what?
To increase.
What happens to the thermal energy of a substance during a physical change of state?
it will increase or decrease depending on the states. from solid --> liquid or liquid --> gas it is positive and endothermic, and thermal energy is increasing from liquid --> solid or gas --> liquid it is negative and exothermic, and thermal energy is decreasing
What is the energy required to change a substance from a solid to a liquid WITHOUT changing it's temperature?
magic of coarse!
What happens to the motion of molecules of matter when an object gains or loses thermal energy?
Increasing temperature means increased kinetic energy on the atomic or molecular level. Temperature of a given substance is the average kinetic energy of the particles of which that substance is composed.
What Explain what happens to the average kinetic energy, thermal energy, and temperature of a substance when the particles in the substance slow down.?
The particles in a substance slow down when the average kinetic energy of the particles decreases. As the average kinetic energy decreases, the internal energy decreases, and so the thermal energy decreases. As the thermal energy of the substance decreases, the temperature decreases.

The phase of matter can be changed by?
changing the temperature or surrounding pressure of a substance
