Q.

How will last molecule evaporate without colliding with other molecule that is how will it get energy to escape?

Q. Soft water does not produce much lather.

1. True
2. False

Q. When a liquid is boiled, the temperature remains the same until all of the __________ becomes a gas.

Q.

Sir

Please guide me about why water vaporates in vaccum?

Q. Water vapours on losing kinetic energy comes down towards the ground
but the other gases donot bhave like this they remain in air so how we can say that water vapours are the gaseous state of water or matter ?

Q. In process of condensation, thermal energy is:

1. given out
2. neither given out nor taken in
3. absorbed
4. not changed

Q. Statement 1: Water shows anomalous behavior below $4^o$C.​
Statement 2: Water molecules in ice are more densely arranged than in liquid water.​

Q. If on a sunny day , too much evaporation happens and forms many heavy clouds , why doesnt it rain the next day ?

Q. An increase in temperature decreases the rate of evaporation.

1. True
2. False

Q.

why does it rain?

Q. Explain water cycle with a suitable diagram?

Q. Describe the water cycle in nature.
