The volume of a gas is 10.0 liters and its pressure is 1.5 atm. If the pressure is decreased to 0.75 atm,

what is its new volume?

The new volume is 20litres

Step-by-step explanation:

This problem bothers on the expansion of gases

According to Boyle's law

The volume of a given mass of gas at constant temperature is inversely proportional to the pressure

P∝1/v

Pv = constant

Given data

P1 = 1.5atm

v1 = 10 litter

P2=0.75atm

v2=?

Applying P1v1 = P2v2

v2 = P1v1/P2

v2 = 1.5*10/0.75

v2 = 15/0.75

v2 = 20litres
