One mole of an ideal monatomic gas undergoes the following four reversible processes :
Step1 : It is first compressed adiabatically from volume `V_(1)` to `1m^(3)`.
Step 2 : then expanded isothermally to volume 10 `m^(3)`.
Step 3 : then expanded adiabatically to volume `V^(3)`.
Step 4 : then compressed isothermally to volume `V_(1)`.
If the efficiency of the above cycle is 3/4 then `V_(1)` is,

One mole of an ideal monatomic gas undergoes the following four reversible processes : Step 1 – it is first compressed adiabatically from volume 8.0m^(3) to 1.0 m^(3) . Step 2 – then expanded isothermally at temperature T_(1) to volume 10.0 m^(3) . Step 3 – then expanded adiabatically to volume 80.0 m^(3) . Step 4 – then compressed isothermally at temperature T_(2) to volume 8.0 m^(3) . Then T_(1)//T_(2)
