Question

Reversible expansion of an ideal gas under isothermal and adiabatic conditions are as shown in the figure. AB arrow Isothermal expansion AC arrow Adiabatic expansion Which of the following options is not correct ? (A) Δ S textisothermal > Δ S textadiabatic (B) TA = TB (C) W textisothermal > W textadiabatic (D) Tc > TA

In adiabatic expansion cooling effect will take place, TC will be less then TA. in adiabatic expansion q = 0 Δ U = w Wpv < 0 Δ U < 0 nCvm Δ T < 0 Δ T < 0 TC - TA < 0 TC < TA

Q. Reversible expansion of an ideal gas under isothermal and adiabatic conditions are as shown in the figure.
AB $\to$ Isothermal expansion
AC $\to$ Adiabatic expansion
Which of the following options is not correct ?

$Δ S_{isothermal} > Δ S_{adiabatic}$

$T_{A} = TB$

$W_{isothermal} > W_{adiabatic}$

$T_{c} > T A$

In adiabatic expansion cooling effect will take place, $T_{C}$ will be less then $T_{A}$ .
in adiabatic expansion $q = 0$
$Δ U = w$
$W p v < 0$
$Δ U < 0$
$n C_{v m} Δ T < 0$
$Δ T < 0$
$T_{C} - T_{A} < 0$
$T_{C} < T_{A}$

ΔSisothermal​>ΔSadiabatic​

TA​=TB

Wisothermal​>Wadiabatic​
