Question

Which of the following choices will favor the melting of ice in a closed container if all other parameters are kept constant?

• A. Adding water with a temperature of $0^{o}C$
• B. Lowering the temperature below $0^{o}C$
• C. Lowering the pressure
• D. Raising the pressure
• E. Decreasing the amount of ice

Answer 1

Answer: (D)

Raising the pressure

Raising the pressure will favor the melting of ice in a closed container if all other parameters are kept constant.
With increase in pressure, the freezing point of ice will be depressed.
Hence, ice will melt.
