Answer:

Adding heat energy to the substance

Step-by-step explanation:

Adding heat energy to a liquid sample would result in an increase in the distance between the individual molecules of the liquid.

According to kinetic molecular theory of matter, the more the temperature of a substance, the more the kinetic energy of the molecules of the substance.

Heat increases the temperature of a substance. The addition of heat to a substance therefore increases the average kinetic energy of the molecules of the substance.

Also, the more the kinetic energy of the molecules in a substance, the more likely for the molecules to drift apart, that is, the average amount of empty space between molecules gets larger.

Hence, the addition of heat energy to a liquid sample would result n an increase in the distance between the individual molecules of the liquid.

Answer:

Adding heat energy to the substance.

Step-by-step explanation:

Thermal energy is associated with the kinetic energy of the particles that make up a body. By adding enough thermal energy to the molecules in a liquid, they overcome the molecular forces and separate, so that the substance becomes a gas; this is a phase change process.

The higher the temperature, the higher the energy of the particles and the higher the speed of the particles.
