Question

6. With the help of an activity, demonstrate that liquids exert pressure.
7. Explain an activity to study the effect of atmospheric pressure.​

Answer 1

Explanation:

6. Activity :A liquid exerts equal pressure at the same depth

1)A liquid exerts pressure on the walls of its container. 2)A liquid exerts equal pressure at the same depth. The formation of fountains of water from the leaking pipes of water supply pipeline tells us that water exerts pressure on the walls of its container.

7. Atmospheric pressure is an indicator of weather. When a low-pressure system moves into an area, it usually leads to cloudiness, wind, and precipitation. High-pressure systems usually lead to fair, calm weather. A barometer measures atmospheric pressure, which is also called barometric pressure.
