Question

Column I gives certain thermodynamic changes and Column II contain the answers for questions in column I. Match them.

Answer 1

(B) Since volume remains constant P/T = Constant
$\frac{P}{T}=\frac{P\left(\frac{1004}{100}\right)}{T+1}$
T = 250 K
(A) $△T_A=\frac{\Delta O}{C_p}$
$\Delta T_B=\frac{\Delta O}{C_{\vee }}$
$\frac{\Delta T_B}{\Delta T_A}=\frac{C_p}{C_v}=\frac{7}{5}$
for diatomic gas
$\Delta T_B=\frac{7}{5}\times 30=42K$
(D) $\sqrt{\frac{3RT}{M}}=\sqrt{\frac{3R{T}^{\prime }}{M^{\prime }}}$

.$\cdot .\frac{T^{\prime }}{T}=\frac{M^{\prime }}{M}$
$T^{\prime }=T\times \frac{M^{\prime }}{M}=\frac{320\times 64}{32}=640K$

(C) 450 K
