Answer the following
1. When water is boiled, the heat energy is transferred to the molecules of water, which begin to move more quickly. They form gaseous molecules of water vapor, which float to the surface as bubbles and travel into the air.
2. When the wind blows gently, it is called breeze.
3. A cloudy night is warmer than a clear night, due to the fact that the sun heats up the land during the day time, at night all the heat goes away into the atmosphere. But when it is cloudy, the clouds insulate the warmth, causing it to be warmer.

Answer:
Explanation:
B. 1) False
2) True
3) False
4) False
5) False
C. 1) When water is boiled at 100°C, it turns into its gaseous state which is water vapour.
2) When wind moves gently and swiftly it is known as a breeze.
3) The cloudy skies are like a barrier. The warmer air on the ground with us tries to leave but the clouds stop it from leaving. Warmer air is light and so it tries to move up but it cannot do so because of the clouds. That is why cloudy nights are warmer than clear nights.
