2.5 L of a sample of a gas at `27^(@)C` and 1 bar pressure is compressed to a volume of 500 mL keeping the temperature constant, the precentage increase in the pressure is:

A

1

B

4

C

5

D

0.8

Text Solution

Verified by Experts

The correct Answer is:
B
`P_(1)V_(1) = P_(2) V_(2)`
`1 xx 2.5 = P_(2) xx (1)/(2)`
`P_(2) = 5` bar
% Increase `= ("Increase in pressure")/("Initial pressure") xx 100`
`= (4)/(1) xx 100 = 400%`
