"in the idea has law" ????
P = k/V
if P=30, V = 150
30 = k/150
k= 4500
then P = 4500/V
so when V = 50
P = 4500/50 = 90
The pressure is 90 p.s.i.
Pressure and volume vary inversely in the idea has law. The pressure exerted by a gas of volume 150cubic inches is 30 p.s.i. Find the pressure exerted by the gas if the volume is decreased to 50cuboc inches
