Question

14.What happens when the kinetic energy of a substance increases?

Answer 1

Knowing this, as the kinetic energy of molecules in a substance increases, the temperature of the substance increases.

Answer 2

When the temperature of an object increases, the average kinetic energy of its particles increases. 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.
