Answer 2

Topic

Pressure

Prerequisite

Pressure

Pressure is defined as Force per unit area.

P = F / A

P is Pressure

F is Force

A is Surface Area

Answer

Choose the correct option

1) Surface Area

Straps of bag is made broader to reduce Pressure. So, Surface Area is increased.

2) More

If surface area will be less for a constant Force then Pressure will be more.

3) Altitude

4) 100kPa

5) Manometer

Manometer is used to measure Liquid Pressure.

True or False

1) True

By definition of Pressure, it is true.

2) True

Air exerts pressure on all walls of container.

3) True

P = Density × Gravity × Height

For a constant height, gravity is same everywhere. The density is constant for a liquid. Hence, pressure will be same at same depth.

4) False

Pressure decreases with Increase in Surface Area.

5) False

Liquids exert pressure on immersed objects.
