A fixed mass of a gas is first heated isobarically to double the volume and then cooled isochorically

A

2

B

`1//2`

C

1n 2

D

1n 3

Text Solution

Verified by Experts

The correct Answer is:
C
c. `Delta W_(ABC) = 2 P (2V - V) = 2PV`
`Delta W_(ADC) = nRT 1n (2V//V)`
`= 2 PV 1n 2`
Therefore, the required factor will be
`(2PV 1n 2)/(2 PV) = 1n 2`

A fixed mass of a gas is adiabatically made to expand to double its volume and then isochorically heated to bring the gas to the original pressure. The ratio of final to initial temperature will be

Certain amount of an ideal gas is expanded isobarically to double its volume. Work obtained in the process is -20 kJ. If same expantion in volume is carried out isothermally irreversibly in single step, calculate the magnitude of work (in kJ).

An ideal gas at initial temperature 300 K is compressed adiabatically ( gamma = 1.4 ) to (1/16)^(th) of its initial volume. The gas is then expanded isobarically to double its volume. Then final temperature of gas round to nearest integer is:
