Q. One mole of an ideal monatomic gas undergoes the following four reversible processes:

S t e p 1

- it is first compressed adiabatically from volume

8.0 m^{3}

1.0 m^{3}

S t e p 2

- then expanded isothermally at temperature

T_{1}

to volume

10.0 m^{3}

S t e p 3

- then expanded adiabatically to volume

80.0 m^{3}

S t e p 4

- then compressed isothermally at temperature

T_{2}

to volume

8.0 m^{3}

.
Then
