What happens to particles of a substance when thermal energy is added to the substance?
It gets warmer.
Why may the temperature of substance change when energy is added?
The energy has to go somewhere. If heat energy is added, it will either increase the temperature, or change the state of matter of the substance.
How does the behaviour of particles change as energy is added to particles?
energy makes particles move.The more energy the particles have,the faster they can move and they farther apart they can get.
What has to be added to a substance to cause a phase change?
Heat energy must be added to or subtracted from a substance to cause a phase change.
What happens when particles in a substance when energy is removed?
The substance's particals will start slowing down and come closer together. As kinetic energy is removed from a substance, it will do the opposite as when kinetic energy is added to a substance.
What happens to the particles of a substance when thermal energy is added to the substance?
It's particles move faster

Heat is what in motion?
As energy is added to a substance, the particles that make up the substance vibrate faster. This is what causes substances to change state (solid to liquid to gas). As the particles move faster, the structure changes.

What happens to particles inside of a solid liquid or gas when energy is added compared to when energy is removed?
When energy is added the particles inside the substance vibrate more. Conversely, the vibrate less when energy is removed.
What is a measure of the energy of motion of particles in a substance?
Particle motion increases as energy (like heat) is added. The motion slows as energy leaves. Temperature is a measure of this change in particle motion.

Which change in state requires that energy be added to the substance?
vaporizing
How will a substance change if energy is added to the liquid at 20 degrees Celsius?
The substance will get hawter
