- 3. a measure of the average kinetic energy of particles in a substance
- 5. a graph that shows how the temperature of a substance increases as it absorbs heat over time
- 6. the transfer of thermal energy from one object or substance to another due to a difference in temperature, always moving from warmer to cooler areas until equilibrium is reached
