Question

Which statement below best explains the relationship between thermal energy and the particles of matter in an object?


A.

As particle movement increases, thermal energy remains unchanged.


B.

As particle movement decreases, thermal energy increases.


C.

As the kinetic energy of the particles increases, the thermal energy will decrease.


D.

As the kinetic energy of the particles increases, the thermal energy will increase.

Answer 1

Answer:

When temperature increases, particles in an object speed up, which means an increase in thermal energy. Since the particles are moving more now, the potential energy decreases, therefore kinetic energy increases.  

Overall, when temp goes up, thermal energy goes up, which leads to an increase in kinetic energy
