1.
The relationship demonstrated by the graph above is a directly proportion relationship.
Charles law states that if a given quantity of gas is held at a constant pressure, its volume
is directly proportional to the absolute temperature. Hence, as the temperature of the gas
increases, the gas molecule will begin to move around more quickly and hit the walls of
the container with more force thus, the volume will increase.

Boyles Law states that the volume of the gas is inversely proportional to the pressure
exerted by the gas.
Pressure vs. Inverse of volume
Boyles law states that the inverse volume of the gas is directly proportional to the
pressure.
