A certain amount of gas of volume V at 27°C temperature and pressure 2 x 10 7 Nm -2 expands isothermally until its volume gets doubled. Later it expands adiabatically until its volume gets redoubled. The final pressure of the gas will be (Use 
=1.5)
Text Solution
Verified by ExpertsThe correct answer is:
B
P =2x10 7 Pa
P 1 V 1 =P 2 V 2
Since V 2 = 2V 1
Hence P 2 = P 1 /2 (isothermal expansion)
P 2 =1x10 7 Pa
