For a physical equilibrium, `H_(2)` O (Ice) `hArr H_(2)` O (Water ) which of the following is the true statement:

Options

A. The pressure change do not affect the equilibrium
B. More of ice melts, if pressure on the system is increased
C. More of liquid freezes, if pressure on the system is increased
D. More of ice melts, if temperature of the system is increased

Answer

To solve the question regarding the physical equilibrium between ice and water, we need to analyze the effects of pressure and temperature on the equilibrium system. The equilibrium can be represented as:

\[ H_2O (s) \rightleftharpoons H_2O (l) \]

### Step-by-Step Solution:

1. **Understanding the Equilibrium:**
- The equilibrium involves ice (solid) and water (liquid).
- Ice has a greater volume than water when it melts.

2. **Effect of Pressure on the Equilibrium:**
- According to Le Chatelier's Principle, if the pressure on a system at equilibrium is increased, the system will shift in the direction that reduces the pressure.
- Since the volume of ice is greater than that of water, increasing the pressure will favor the side with less volume, which is the liquid water side.

3. **Conclusion on Pressure:**
- Therefore, when pressure is increased, more ice will melt to form water. This means that the correct statement regarding pressure is:
- "More ice melts if pressure on the system is increased."

4. **Effect of Temperature on the Equilibrium:**
- The melting of ice into water is an endothermic process, meaning it absorbs heat.
- According to Le Chatelier's Principle, increasing the temperature will favor the endothermic reaction, which in this case is the melting of ice.

5. **Conclusion on Temperature:**
- Thus, when the temperature is increased, more ice will melt into water. This means that the statement:
- "More ice melts if temperature of the system is increased" is also correct.

### Final Answer:
The true statements regarding the equilibrium between ice and water are:
- More ice melts if pressure on the system is increased.
- More ice melts if temperature of the system is increased.
