Vedclass · Answer

(A) From the ideal gas equation,$PV = nRT$,we have $T = \frac{PV}{nR}$.$1$. In the process $A \rightarrow B$,pressure $P$ is constant and volume $V$ increases. Since $T \propto V$ at constant pressure,the temperature increases.$2$. In the process $B \rightarrow C$,volume $V$ is constant and pressure $P$ decreases. Since $T \propto P$ at constant volume,the temperature decreases.$3$. In the process $C \rightarrow D$,pressure $P$ is constant and volume $V$ decreases. Since $T \propto V$ at constant pressure,the temperature decreases.$4$. In the process $D \rightarrow A$,volume $V$ is constant and pressure $P$ increases. Since $T \propto P$ at constant volume,the temperature increases.Comparing the options,the temperature increases as the gas goes from $A$ to $B$.

The following figure shows two processes $A$ and $B$ for a gas. If $\Delta Q_A$ and $\Delta Q_B$ are the amounts of heat absorbed by the system in the two cases,and $\Delta U_A$ and $\Delta U_B$ are the changes in internal energies,respectively,then:

The pressure of an ideal gas varies with volume as $P = \alpha V,$ where $\alpha$ is a constant. One mole of the gas is allowed to undergo expansion such that its volume becomes $m$ times its initial volume. The work done by the gas in the process is

$A$ thermodynamic system is taken from an original state $D$ to an intermediate state $E$ by the linear process shown in the figure. Its volume is then reduced to the original volume from $E$ to $F$ by an isobaric process. The total work done by the gas from $D$ to $E$ to $F$ will be $......J$
