An ideal gas undergoes four different processes from the same initial state as shown in the figure below. Those processes are adiabatic, isothermal, isobaric and isochoric. The curve which represents the adiabatic process among 1, 2, 3 and 4 is

- A1
- B2
- C3
- D4
View written solutionFree
Correct answer: B
$${\left( {{{dP} \over {dV}}} \right)_{adiabatic}} = - \gamma P$$
$${\left( {{{dP} \over {dV}}} \right)_{isothermal}} = -P$$
$${\left( {{{dP} \over {dV}}} \right)_{adiabatic}} \gt {\left( {{{dP} \over {dV}}} \right)_{isothermal}}$$
