Answer 1

Pascal's law states that any pressure applied to a fluid in a closed system exerts an equal pressure in all the directions of the fluid.

Explanation:

• The atmospheric pressure can be measured with the help of barometer by balancing the weight of the mercury inside the glass tube.
• If the atmospheric pressure is high when compared to that of the weight of the mercury, then the mercury levels rise indicating an high pressure.
• If the outside atmospheric pressure is less, then the mercury levels will lower down.
