Question

For a given mass of gas at constant temperature ,if the volume V becomes four times,the pressure P will be

Answer 1

Answer:

Since Pressure is inversely related to Volume, When volume increases 4 times, Pressure decrease to one fourth

Answer 2

Answer:

the pressure becomes 1/4th

Explanation:

From Boyle's law

P1*V1=P2*V2 at constant T

if the volume becomes 4 times then V2=4V1

so

P1*V1= P2 * 4V1

or. P1=4P2

or P2=P1/4
