Question

What is the relationship between kinetic energy and thermal energy?
(1 point)
• Kinetic energy is the transfer of thermal energy.
As the kinetic energy in a substance's atoms increases, its thermal energy decreases, and vice versa.
As the kinetic energy in a substance's atoms increases, its thermal energy increases, and vice versa.
O Kinetic energy is a measure of thermal energy.

Answer 1

As the kinetic energy in a substance's atoms increases, its thermal energy increases, and vice versa.

Explanation: Thermal energy (internal energy) depends largely on the kinetic energy of a substance's particles (their motion). More particle motion → higher average kinetic energy → higher thermal energy (and usually higher temperature).
