ACT Preparation / Unit 22 ACT 2123 short lesson, about 20 seconds
Heat and Temperature
Captions available
The idea
Temperature is related to the average kinetic energy of the particles in a substance. Heat is the transfer of energy caused by a temperature difference, flowing from hotter to colder.
In practice
A hot spoon in cool water loses energy to the water until both reach the same temperature.
Where people slip
Temperature describes a substance; heat is energy moving between substances.
