When we heat water, it gets converted into steam. If we cool steam, it gets converted into water. When we freeze water, it gets converted to ice. When ice is heated it melts to give water. What type of changes occur in these processes?

Ice to water and water to ice, water to steam and steam to water are all physical and reversible changes. By changing the temperature, one form can be converted into other.
