PROCESS OF CHANGE OF STATES OF MATTER:
• Vaporization
• Condensation
• Freezing
• Melting
• Sublimation
• Evaporation
VAPORIZATION:(CHANGE OF LIQUID INTO GAS):
The process of change of water into vapor is called vaporization. When water is heated after reaching at 100°C water starts boiling. At this temperature water turns into vapour. Since, water boils at 100°C, hence 100°C is called the boiling point of water.
BOILING POINTS
The common definition of boiling point is, the temperature at which a liquid boils is called its boiling point. Different liquid boils at different temperatures.
CONDENSATION:(CHANGE OF GAS INTO LIQUID)-
The change of vapor into water because of decrease in temperature is called condensation. Condensation is the reverse process of vaporization. When the temperature of vapor decreases it changes into water, this process is known as condensation.
Distilled water is manufactured by the condensation of vapor. The process of making of distilled water is known as distillation. In distillation first water is boiled to vaporize and the vapor is cooled, i.e. condensed to get distilled water.
FREEZING:(CHANGE OF LIQUID INTO SOLID) -
The change of liquid into solid because of decrease in temperature is called freezing. Water change into ice because of decrease in temperature, in other words water freezes into ice because of decrease in temperature. Water freezes at 0°C.
MELTING:(CHANGE OF SOLID INTO LIQUID)
The change of solid into liquid due to increase in temperature is known as melting. Ice, which is a solid melts, i.e. changes into water at 0°C.
