Question

What are the interchanges of matter in water? What are the three forms of water?

Answer 1

Hint :The change of state of matter from one state to another and back to the original state of matter is known as interconversion of matters. The change can be physical or chemical depending upon the temperature, pressure and other factors.

Complete Step By Step Answer:
Water is the only substance on Earth that naturally occurs in three physical states: solid, liquid and gas. Depending on temperature and atmospheric pressure, water can change from one state to another, known as physical phase change.
The three interchange forms of water are:
Ice to water- Melting
Water to water vapor- evaporation
Water to ice- Freezing
Melting: The change of solid into liquid due to increase in temperature is known as melting. Ice, which is a solid form of water melts, i.e. changes into water at $0^\circ $ C. It occurs when the internal energy of a solid increases, usually through the application of heat or pressure, such that the molecule becomes less ordered.
Evaporation: The process by which an element or compound transitions from its liquid state to its gaseous state below the temperature at which it boils. They transfer energy to each other as the molecules of the liquid collide, depending on how they collide with each other. The liquid particles will generally escape and enter the surrounding air as a gas.
Freezing: The process through which a substance changes from a liquid to a solid when its temperature is lowered below its freezing point. The molecules in the liquid state are loosely bound, and the intermolecular forces of attraction are lower than that of solids. This is because the heat energy transferred to the molecule during the process of conversion from solid to the liquid state is larger than the potential energy of the molecule holding them together in the crystal lattice of a solid.

Note :
Water molecules in water vapor have few hydrogen bonds and more space between them, making vapor light and less dense than water or ice. While the ${H_2}O$ molecules are closer together in liquid water than in solid ice, there are fewer hydrogen bonds in liquid water than in the rigid lattice of ice. Therefore, water is fluid whereas ice is solid.
