As atoms gain energy, they move faster and slide past one another more easily. atoms at the surface of the substance overcome attractions to nearby atoms and break free of the surface.
which change of state is taking place?
liquid to gas
gas to liquid
liquid to solid
solid to liquid

Option (a) is the correct answer.

Explanation:

Particles of a solid are held by strong intermolecular forces of attraction due to which they are not able to move from their initial place unless an external force or pressure is applied.

In liquids, molecules are less strongly held by each other as compared to solids and they are able to slide past each other. Therefore, liquids occupy volume of a container in which they are kept.

In gases, molecules are far apart from each other as they are held by weak Vander waal forces. Hence, particles of a gas have high kinetic energy and they are able to diffuse readily into the atmosphere or surroundings.

Thus, we can conclude that in the given situation a change from liquid to gas is taking place.

protons in

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
