Question

factors that affect thermal energy

1. ____________ - higher = faster particle motion = more energy
2. ____________ - more particles = more total thermal energy
3. ____________ - some substances store more heat than others

Explanation:

1. Temperature is related to average kinetic - energy of particles. Higher temperature means faster - moving particles and more thermal energy.
2. Mass (or number of particles) affects total thermal energy. More particles mean more total energy.
3. Specific heat capacity of a substance determines how much heat it can store for a given temperature change.

Answer:

1. Temperature
2. Mass (or number of particles)
3. Specific heat capacity
