Question 924: Thermodynamics & KTG

Question

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

Accepted Answer

${\left( {{{dP} \over {dV}}} \right)_{adiabatic}} =  - \gamma P$
${\left( {{{dP} \over {dV}}} \right)_{isothermal}} = -P$
${\left( {{{dP} \over {dV}}} \right)_{adiabatic}} > {\left( {{{dP} \over {dV}}} \right)_{isothermal}}$
