The density of air is 1.3 kg/m³. What mass of air is contained in a room measuring 2.5 m x 4 m x 10 m?

Two vessels A and B have the same base area and contain water up to the same height, but the mass of water in vessel A is four times that of water in vessel B. The ratio of pressure on the base of vessel A to that on the base of vessel B is

In which of the following cases will the increase in pressure be the greatest?

Read the following statements and choose the correct option.

Statement A: At the mountains, the water boils at a temperature less than 100°C.
Statement B: At the top of mountains, the atmospheric pressure is less than pressure at sea-level.

Choose the correct statements from the following.

(A) Blood pressure is minimum at our feet and maximum at our head.
(B) It is easier for a camel to move on the sand because its feet have a large area.
(C) The pressure along a horizontal line in a vessel filled with water is the same.
