Project Physics:
Pawantook a glass of water and submerged it in a trough containing water. He observed that on lifting the glass the water was not flowing out. He rushed to his elder brother Madan as he thought it was a kind of magic. Madanthen explained that it was due to atmospheric pressure.

1. In which direction atmospheric pressure is acting?
2. In which direction weight of water is acting.?
3. What value does Madanshow?

A little boy was playing tug of war with his elder brother; he tried everything but was unsuccessful in pulling the rope towards himself.

Statement1: Elder brother was capable of applying a greater force than his younger brother and hence the net force was in a direction to make him win.

Yaavan wanted to check the process of evaporation. He was very excited to practically check it. So, he brought a glass of water and put it on a table. He thought of leaving the glass for 5-10 days. Just when he thought everything is fine and he can leave the glass there, a doubt came to his mind. He did not heat the water in the glass.

Now can you help him and tell whether supplying heat is necessary condition for evaporation?

Q. Rakesh did an experiment in which he kept his pencil inside a glass of water. He observed that the pencil bent along its length inside the water. He repeated the experiment by changing the medium to oil and glycerine and noticed the same observation but the amount of bending was different in each case.

On looking from the top, Rakesh found that the bottom of the glass appeared _________.
