Chapter: 11
| PART – II |
| IMPORTANT QUESTION ANSWER |
A. Answer the following Question:
(i) Define evaporation.
Ans: Evaporation is the process by which water changes from liquid to gaseous state due to heat.
(ii) What is melting?
Ans: Melting is the process of changing solid water (ice) into liquid water by heating.
(iii) What is the water cycle?
Ans: The water cycle is the continuous movement of water between the earth and atmosphere through evaporation, condensation, and precipitation.
(iv) What is sublimation?
Ans: Sublimation is the process where solid water (ice) changes directly into water vapor without becoming liquid.
(v) Explain why water droplets form on the outside of a cold glass.
Ans: Water vapor in the air condenses into droplets when it touches the cold surface of the glass.
(vi) Why does water evaporate faster on a hot day compared to a cold day?
Ans: Water evaporates faster on a hot day because heat provides the energy needed for water molecules to escape from the liquid phase into the gas phase. Higher temperatures increase the rate of evaporation by allowing more molecules to gain enough energy to break free from the surface of the water.
(vii) What is the role of the water cycle in maintaining life on Earth?
Ans: The water cycle plays a crucial role in maintaining life on Earth by continuously recycling water. It ensures the availability of fresh water through processes like evaporation, condensation, and precipitation, which helps support plant growth, sustain ecosystems, and provide water for human consumption.
B. Fill in the Blanks:
(i) Water changes from solid to liquid by a process called ______________.
Ans: Melting.
(ii) Dew is formed due to _______________of water vapor on cold surfaces.
