What is temperature a measurement of?
The average KE of particles

What is heat?
Heat is a measurement of energy on an absolute scale
3 of 9
How is energy transferred by conduction?
The transfer of KE between particles due to free electrons
4 of 9
How is energy transferred by convection?
The expansion of a liquid or gas when it's heated causes a change in density (normally less dense) which causes it to rise and results in bulk fluid flow

How is energy transferred by radiation?
Infrared radiation is an electromagnetic wave and needs no medium(can travel through vacuum).

Why does temperature not change during a change of state?
When a substance changes state, energy is needed to break the bonds that holds molecules together.
