Which may be true for a substance that absorbs energy?

a.
the energy decreases the molecular motion but increases the kinetic energy of the substance.
b.
the energy increases the molecular motion and the kinetic energy of the substance.
c.
the energy decreases the molecular motion and the kinetic energy of the substance.
d.
the energy increases the molecular motion but decreases the kinetic energy of the substance

Option (B) is the correct answer.

Explanation:

When energy is absorbed by a substance then there will occur an increase in motion of molecules of the object. As a result, they start to move rapidly from one place to another.

This will lead to change in the phase or state of substance.

For example, an ice cube when placed at room temperature then it absorbs heat energy from its surroundings. Due to this solid state of water (ice) changes into liquid state.

Thus, we can conclude that the statement energy increases the molecular motion and the kinetic energy of the substance, is true for a substance that absorbs energy.
