Boyle's Law
As pressure of a gas at constant temperature increases, volume decreases
Pressure of a Gas
is force of outward push over an area of the walls of a container.

Difference between direct and indirect
Directly Proportional: As one variable increases, the other variable also increases
Indirectly Proportional: As one variable increases, the other variable decreases
Power =
force x velocity
When gas is involved
We use pistons.
