Question

A gas is compressed isothermally to half of its volume. By what factor
does the pressure of the gas increase ? ( 1.4)​

Answer 1

Answer:

2 times

Explanation:

The ideal gas equation is given as;

PV = nRT

Now in an isothermal reaction, we know that temperature of the system will remain constant. Hence we can write as;

P1V1 = P2V2

Now if V2 = Half of V1

V2 = 0.5V1

P1 V1 = 0.5V1 x P2

P2 = 2 P1

It means that the final pressure will be twice than the initial pressure
