Question

What happens to water molecules that form the ice on a road when temperatures rise and the ice begins to melt?a)As temperature increases, the water molecules begin to move farther apart as they lose kinetic energy and form a liquid.b)As temperature increases, the water molecules begin to move closer together as they gain kinetic energy and form a liquid.c)As temperature increases, the water molecules begin to move farther apart as they gain kinetic energy and form a liquid.

Answer 1

Answer:

The correct answer is option c.

Explanation:

Solid state : It is a state in which the particles are closely packed and does not have any space between them. They have least kinetic energy due to restricted movement. This state has a definite shape and volume.

Liquid state : It is a state in which the particles are present in random and irregular pattern. The particles are closely arranged but they can move from one place to another and thus have higher kinetic energy as compared to solids. This state has a definite volume but does not have a fixed shape.

Gaseous state : It is a state in which the particles are loosely arranged and have a lot of space between them. They have highest kinetic energy. This state has indefinite volume as well as shape.

So, when water molecules that forms ice melts it gains kinetic energy due to  increase in temperature by which they gain kinetic energy and starts moving away from each other converting their state from solid to liquid.

Answer 2

Answer:

The kinetic energy of the water particles decreases.
