Q. The P-T graph as given below was observed for a process of an ideal gas, which of the following statement is true?

$w = + v e, Δ H = + v e$

$w = - v e, Δ H = - v e$

$w = - v e, Δ H = + v e$

$w = + v e, Δ H = - v e$

$V_{B} > V_{A} an d T_{B} > T_{A}$
$Δ H = n c_{p} (T_{B} - T_{A}) > 0$
$w = - p_{e x t} (V_{B} - V_{A}) < 0$

Q. The P-T graph as given below was observed for a process of an ideal gas, which of the following statement is true?

w=+ve,ΔH=+ve

w=−ve,ΔH=−ve

w=−ve,ΔH=+ve

w=+ve,ΔH=−ve

VB​>VA​andTB​>TA​ ΔH=ncp​(TB​−TA​)>0 w=−pext​(VB​−VA​)<0

$w = + v e, Δ H = + v e$

$w = - v e, Δ H = - v e$

$w = - v e, Δ H = + v e$

$w = + v e, Δ H = - v e$

$V_{B} > V_{A} an d T_{B} > T_{A}$
$Δ H = n c_{p} (T_{B} - T_{A}) > 0$
$w = - p_{e x t} (V_{B} - V_{A}) < 0$
