### Forces in Fluids

Pressure:the amount of force exerted per unit of area

P=F/A

A pascal (Pa) is the unit of pressure

1 Pa = 1N/m2

Fluid

a substance that assumes the shape of its container

Is a liquid a fluid?

YES

Is a solid a fluid?

NO

Is a gas a fluid?

YES

Charles’ Law

The volume of a gas increases with increasing temperature provided the pressure does not change.

constant

P T V

Boyle’s Law

If you decrease the volume of a container of gas the pressure of the gas will increase provided the temperature does not change

constant

P T V

Pop Bottle Demonstration

Shaking the bottle increases the pressure.

Opening the bottle quickly decreases the pressure.

This causes a rapid increase in volume.
