Gaseous StateHard

Question

2.5 L of a sample of a gas at 27oC and 1 bar pressure is compressed to a volume of 500 mL keeping the temperature constant, the percentage increase in pressure is 

Options

A.100 %
B.400 %
C.500%
D.80%

Solution

Using p1V1 = P2V2 1 × 2.5 = 0.5 × P2 = 5 bar.
∴  % increase in pressure = ×  100% = 400 %.
