Question
Higher temperatures cause particles to move quicker, resulting in greater ____.
- Kinetic energy
- Thermal energy
- Kinetic and thermal energy
- None
Hint:
Kinetic and thermal energy
The correct answer is: Kinetic and thermal energy
With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion.
When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.
