Answer 1

The kinetic energy of particles in a substance can change when the substance changes state. The balance between the kinetic energy and intermolecular forces determines the state of the substance. Heating, cooling, and increasing pressure can affect the kinetic energy and change the physical state of a substance.

Step-by-step explanation:

The state of a substance depends on the balance between the kinetic energy of the individual particles (molecules or atoms) and the attractive forces between molecules, called intermolecular forces. Heating and cooling can change the kinetic energy of the particles in a substance, and so, we can change the physical state of a substance by heating or cooling it. Increasing the pressure on a substance forces the molecules closer together, which increases the strength of intermolecular forces.
