Question:
If solid tin is in equilibrium with its vapor, the degree of freedom is (answer in integer) .............
If solid tin is in equilibrium with its vapor, the degree of freedom is (answer in integer) .............
Show Hint
At equilibrium between phases, the Gibbs phase rule is the fastest way to calculate degrees of freedom. Remember: a two-phase single-component system always has one degree of freedom.

Correct Answer: 1
Solution and Explanation
Step 1: Recall Gibbs phase rule.
The formula is: \[ F = C - P + 2 \] where: - \(F\) = degrees of freedom, - \(C\) = number of components, - \(P\) = number of phases.
Step 2: Identify components and phases.
- Substance: tin (Sn) → only one chemical species present. \[ C = 1 \] - Phases: solid tin + vapor phase. \[ P = 2 \]
Step 3: Apply Gibbs phase rule.
\[ F = C - P + 2 = 1 - 2 + 2 = 1 \] Final Answer:
\[ \boxed{1} \]

- The triple point \((T_t, P_t)\) is shown in a schematic phase diagram (pressure (P) – temperature (T) plot) for a one–component system. \(G_S, G_L\) and \(G_V\) are the free energies of solid, liquid, and vapor, respectively. At a constant pressure, \(P_t\), the correct free energy (G) versus temperature (T) plot is:
- The standard free energy change for the reaction \[ SO_2 + \tfrac{1}{2}O_2 \rightleftharpoons SO_3 \] is given by \(\Delta G^\circ = -94600 + 89.37T\) (J). At \(T=1050\,K\), the equilibrium constant \(K_p\) is (rounded off to two decimal places). Given: Universal gas constant \(R=8.314\,J\,mol^{-1}K^{-1}\).
- A tank is divided into two compartments with one compartment containing a gas at a given pressure, while the second is completely evacuated. If the partition is removed, the gas occupies the entire compartment. Which one of the following statements is CORRECT?
- A cylinder of volume \(0.1 \, m^3\) is filled with nitrogen at \(10 \, MPa\) and \(300 \, K\). Consider nitrogen to be an ideal gas. The cylinder develops a leak and nitrogen escapes to the atmosphere which is at \(0.1 \, MPa\). After some time, the pressure in the cylinder reduces to \(5 \, MPa\). Assuming the cylinder and the leaked gas temperature remains constant at \(300 \, K\), the work done (in MJ) by nitrogen gas is:
- A closed system undergoes a process 1–2 in which it absorbs 150 kJ of energy as heat and does 90 kJ of work. Then it follows another process 2–3 in which 80 kJ of work is done on it while it rejects 60 kJ as heat. If it is desired to restore the system to the initial state (state 1) by an adiabatic path, the work interaction (in kJ) in this process will be
