What does a substance gain or lose when its temperature changes?
The density of the substance becomes higher because of the particles slow down and move closer together when the substance cools.
What happens to thermal energy if the molicules speed up?
If molecules speed up, they gain kinetic energy which increases the thermal energy of the substance. This causes the temperature of the substance to rise since thermal energy is directly related to the average kinetic energy of the molecules.
What happens to the particles when thermal energy is added or removed?
When thermal energy is added to a substance, the particles gain kinetic energy and move faster, increasing the substance's temperature. When thermal energy is removed, the particles lose kinetic energy and slow down, causing the temperature to decrease.
Why is heat energy thermal energy?
Heat energy is considered thermal energy because it is the energy associated with the random motion of particles within a substance. When particles are heated, they gain kinetic energy and vibrate more vigorously, increasing the substance's overall thermal energy. This thermal energy can be transferred between objects through conduction, convection, or radiation.
If you heat thermal energy will the particles move faster?
the hotter it is, the faster they are moving

Does a substance gain o lose thermal energy when it evaporates?
A substance gains thermal energy when it evaporates, as energy is required to break the intermolecular forces holding the molecules together and allow them to escape into the gaseous phase.

Does thermal energy depend on amount of substance?
Yes, thermal energy does depend on the amount of substance. The more mass a substance has, the more thermal energy it can store. This is because thermal energy is related to the internal energy of a substance, which increases with the amount of substance present.
What happens when thermal energy is absorbed by a substance?
When thermal energy is absorbed the substance expands to some extent that is if it is a ball it becomes oblated to a very small extent as a balloon expands on blown with air , if it is a lengthy object the length becomes little longer.
What will happen to the molecules or atoms of a substance when it melts?
the atoms will begin to giggle around more as they gain thermal energy.
Where does the heat for get thermal energy come from?
Thermal energy comes from the internal vibrations and movements of atoms and molecules within a substance. When these particles are heated, they gain kinetic energy, causing them to move faster and creating thermal energy in the process.
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 an increase in total energy of the particles in a substance affect the thermal energy of the substance?
How does an increase in the total energy of the particles in a substance affect the thermal energy of the substance.
