Answer

Two Ways to Decrease Pressure on a Surface

Increasing the Surface Area: One of the simplest ways to decrease pressure on a surface is to increase the surface area on which the force is applied. When the same amount of force is applied over a larger area, the pressure decreases. This can be done in a number of ways, depending on the situation. For example:

Using a wider base: A wider base will distribute the weight of an object over a larger area, reducing the pressure on the surface below. This is why many heavy objects have wide, flat bases.

Using a cushion: A cushion can be used to increase the surface area of a chair or other piece of furniture. This will distribute the weight of the person sitting on the chair over a larger area, reducing the pressure on the surface below.

Using shoes with a larger sole: Shoes with a larger sole will distribute the weight of the person wearing them over a larger area, reducing the pressure on the ground below.

Decreasing the Force: Another way to decrease pressure on a surface is to decrease the force being applied to that surface. This can be done in a number of ways, depending on the situation. For example:

Removing weight: Simply removing weight from the surface will decrease the force being applied to it, reducing the pressure. For example, removing books from a stack will decrease the pressure on the bottom book.

Using a lever: A lever can be used to decrease the force being applied to a surface. By spreading the force out over a longer distance, the pressure on the surface can be reduced. For example, using a crowbar to lift a heavy object will decrease the pressure on the ground below.

Using a pulley: A pulley can also be used to decrease the force being applied to a surface. By spreading the force out over a longer distance, the pressure on the surface can be reduced. For example, using a pulley to lift a heavy object will decrease the pressure on the ground below.

By increasing the surface area or decreasing the force, the pressure on a surface can be decreased. It is important to consider the situation and choose the appropriate method to reduce pressure.

Two ways to decrease pressure on a surface : i) By decreasing the amount of force applied. ii) By increasing the surface area on which the force is acting.

Answer

Pressure of a gas can be easily increased or decreased by compressing it or expanding it or by increasing / decreasing the temperature if the volume remains constant.

Pressure of a liquid can be increased by compressing the air or other gas or its own vapour pressure.

Pressure on a solid can be increased by putting it in a hydraulic or mechanical press.
