Question

3.

How much should the pressure be increased in
order to decrease the volume of a gas by 5% at
a constant temperature?​

Answer 1

Explanation:

Let the initial volume be V

Final volume=V-5% of V

=19V/20

At constant temperature, according to Boyles law,

P1V1=P2V2

P1×V=P2×19V/20

P2=20P1/19

5% of initial pressure has to be increased.
