melting
The combined total of the kinetic and potential energy in a material is called ____________.

thermal energy
Why are different substances solids, liquids, or gases at room temperature?
Some substances are affected more by temperature than other substances.
All substances can be solid, liquid, or gas at room temperature, it just depends on how the substance is being used.
Different substances have different melting and boiling points because their particles have attractive force of varying strengths between them.
Substances with more particles will be a gas at room temperature, while substances of fewer particles will be a liquid or a solid.
Adding thermal energy to a cup of water may cause the particles to _________.
move closer together
move faster
slow down
collide less often
Can thermal energy increase even if the kinetic energy is constant?
Yes, because thermal energy is a measure of the total energy of a system which is dependent on the number of particles in the system, the state of the material, as well as temperature.
No, because kinetic energy is the energy of motion, and increasing particle speed is the only way to increase thermal energy.
No, because when thermal energy is increased the kinetic energy increased also.

medium
transverse wave
opaque
