Question 1 :
Assertion: Thermodynamics process in nature are irreversible.
Reason: Dissipative effects cannot be eliminated
Question 3 :
Temperatures of two hot bodies $B_{1}$ and $B_{2}$ are $100^{\circ}C$ and $80^{\circ}C$ respectively. The temperature of surrounding is $40^{\circ}C$. At $t = 0$, the ratio of rates of cooling of the two bodies (liquid) $R_{1} : R_{2}$ will be:
Question 7 :
If there were no atmosphere, the average temperature on earth surface would be<br>
Question 8 :
Entropy change of a system is determined by the initial and final states only, irrespective of how the system has changed its states.<br>If true enter 1 else 0<br>
Question 14 :
Which of the following state function not zero at standard state?<br/>
Question 15 :
The change in enthalpy, $\Delta H$ accompanying a process depends on the path followed.<br/>
Question 16 :
The state of a gas can be described by quoting the relationship between ________.
Question 17 :
Use the given standard enthalpies of formation to determine the heat of reaction of the following reactions:<br>$TiCl_{4}(g) + 2H_{2}O(g) \rightarrow TiO_{2}(g) + 4HCl(G)$<br>$\triangle H_{f}^{\circ}TiCl_{4}(g) = -736.2\ kJ/mole\ \triangle H^{\circ}_{f} TiO_{2}(g) = -944.7\ kJ/mole$<br>$\triangle H_{f}^{\circ} H_{2}O(g) = -241.8\ kJ/mole\ \triangle H^{\circ}_{f} HCl(g) = -92.3\ kJ/mole$.
Question 19 :
Two closed vessel $A$ and $B$ of equal volume of $8.21L$ are connected by a narrow tube of negligible volume with open valve. The left hand side container id found to contain $3\ mole \, CO_2$ and $2\ mole$ of $He$ at $400K$. What is the partial pressure of $He$ in vessel $B$ at $500K$?
Question 20 :
An insulated container of gas has two chambers separated by an insulating partition. One of the chambers has volume $V_1$ and contains ideal gas at pressure $P_1$ and temperature $T_1$. <br/>The other chamber has volume $V_2$ and contain same ideal gas at pressure $P_2$ and temperature $T_2$. If the partition is removed without doing any work on the gas, the final equilibrium temperature of the gas in the container will be:
