at constant temperature the pressure of a gas is inversely proportional to its volume.If certain amount of a gas occupies a volume of 30cc and exerts a pressure of 85 g/,cm square ,then find the decrease in its pressure when the same amount of gas occupies a volume of 75cc.

Answer:
Step-by-step explanation:
P is inversely proportional to volume
it means
p1/p2 = v2/v1
Therefore ATQ
85/p2 = 75/30
p2=17
decrease in pressure = p1-p2
= 85-17 = 68
