Vedclass · Answer

(B) In an isothermal process,the temperature $T$ remains constant. In an adiabatic process,the relationship between variables is governed by $PV^{\gamma} = 	ext{constant}$,$TV^{\gamma-1} = 	ext{constant}$,and $T^{\gamma}P^{1-\gamma} = 	ext{constant}$.$(a)$ In a $P-V$ graph,an isothermal process is a curve $PV = 	ext{constant}$,and an adiabatic process is a steeper curve $PV^{\gamma} = 	ext{constant}$. The graph shows a vertical line for adiabatic,which is incorrect.$(b)$ In a $P-T$ graph,an isothermal process is a vertical line $(T = 	ext{constant})$. The graph shows a horizontal line,which is incorrect.$(c)$ In a $V-T$ graph,an isothermal process is a vertical line $(T = 	ext{constant})$. An adiabatic process follows $TV^{\gamma-1} = 	ext{constant}$,which is a curve. This graph is correct.$(d)$ In a $P-T$ graph,an isothermal process is a vertical line $(T = 	ext{constant})$. An adiabatic process follows $T^{\gamma}P^{1-\gamma} = 	ext{constant}$,which is a curve. This graph is correct.Thus,graphs $(c)$ and $(d)$ are correct.
