An ideal gas at initial pressur e`P_(1)` and volume `V_(1)` undergoes reversible expansion to the same volume `V_(f)` either isothermally or adiabatically . Consider the following statements `:`
1. `|P_(f)(` adiabatic `) lt P_(f)(` isothermal `)|" "` 2. `|W(` adiabatic `) |lt|W(` isothermal `)|`
3. `|T_(f)(` adiabatic `) lt T_(f)(` isothermal `)|" "` 4. `|q(` adiabatic `)|lt|q(` isothermal `)|`
where the symbols have their usual meaning.
How many statements of the above are correct?

Options

A. Only one
B. Only two
C. Only three
D. All

Answer

4

Explanation

`{:(1.,|P_(f)("adiabatic")ltP_(f)("isothermal")|),(2.,|W("adiabatic")|lt|W("isothermal")|),(3.,|T_(f)("adiabatic") lt T_(f)("isothermal")|),(4.,| q("adiabatic")| lt|q("isothemal")|):}`
