Bob has a cup of hot chili. it is too hot to eat.
after ten minutes, the chili is cool enough for him to eat.
what has happened to the chili's thermal energy?

a.
it has increased the chili's kinetic energy.
b.
it has increased the chili's potential energy.
c.
it has increased the air's potential energy.
d.
it has increased the air's thermal energy.

B.  It has increased the chili's potential energy

Explanation:

When there is an increase in the kinetic energy of a substance, the vibrations of atoms and molecules of the substance increases.

This kinetic energy increases the thermal energy of the substance.

So, when there is a decrease in the thermal energy of a substance, the kinetic energy decreases because the random motion of the molecules or atoms becomes feeble.

If the kinetic energy of the substance decreases, the potential energy of the substance increases.

So, if the chili has cooled after 10 minutes, it has increased the potential energy of the substance.
