Heat Versus Temperature
Learning Objective
I can differentiate between heat and temperature at the molecular level.
Key Concepts
Temperature is the average kinetic energy of a substance, while heat is the flow of kinetic energy.
Heat always flows from hot to cold objects due to collisions and transfer of kinetic energy between particles.
When two objects reach the same temperature, they are in equilibrium, meaning the rate of kinetic energy transfer between them is equal.
