Question

The work done on the system when one mole of an ideal gas is compressed isothermally to a final
volume of 0.01 m at constant external pressure of 5 bar is 20 kJ. What is initial volume of the gas?
1) 0.05 m
2) 0.025 m
3) 0.04 m
4) 0.03 m​

Answer 1

answer is( D)0.05m3

w=-P (v2-v1)

-20*10^3 /5*10^5)+. 01
