Answer:
When the pressure of gas is double the volume will decrease by the same factor.
Step-by-step explanation:
According to the Bolye's law,
The pressure of given amount of gas at constant temperature and amount of gas is inversely proportional to its volume.
Mathematical relationship:
P∝1/V
P = K/V
PV = K
P₁V₁ = P₂V₂
P₁ = initial pressure
V₁= initial volume
P₂= final pressure
V₂=final volume
So by increasing the pressure volume will decrease, or by decreasing the pressure volume will increase. The temperature and mole of gas are kept constant and pressure and volume changed by same factor.
