Question:
Ice and water are placed in a closed container at a pressure of 1 atm and temperature 273.15K. If pressure of the system is increased 2 times, keeping temperature constant, then identify correct observation from the following:
Ice and water are placed in a closed container at a pressure of 1 atm and temperature 273.15K. If pressure of the system is increased 2 times, keeping temperature constant, then identify correct observation from the following:
Show Hint
Le Chatelier's principle can help predict how pressure changes affect the phases of a substance in equilibrium.
Updated On: Feb 3, 2026
- Volume of system increases.
- The amount of ice decreases.
- Liquid phase disappears completely.
- The solid phase (ice) disappears completely.
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Increasing the pressure at constant temperature will push the equilibrium towards the liquid phase (since the solid phase occupies less volume). As a result, the amount of ice decreases.
Final Conclusion:
The correct answer is Option (2), the amount of ice decreases.
