States of Water
Change of state: The state of water can be changed by changing the temperature, i.e. by heating or cooling.
Water freezes to form ice: Fill an ice tray with water and keep it in the freezer of a refrigerator to coot it. Take out the tray after 2—3 hours. When water is cooled, it forms ice. This is known as freezing of water.
Ice melts to form Liquid water: Keep a few ice cubes in a plate outside the refrigerator. When ice is heated, it melts quickly to form water. This is known as melting of ice.
Water evaporates to form water vapour: When water is heated, it changes to form water vapour, a gas. This is known as evaporation. Though some evaporation takes place at all temperatures, a hot liquid evaporates faster than a cold liquid. Wet clothes become dry because the water in the clothes slowly evaporates. Heat water in a pan-till it boils. Steam is formed and the quantity of water reduces quite rapidly.
Water vapour condenses to form water: Take water in a beaker and add a few ice cubes to it to make the water cold. As the air in contact with the tumbler cools down, the water vapour present in the air condenses to form water. Thus, when water vapour is cooled, it changes back to water. This is known as condensation.
