Question

A piece of ice at $0^{\circ }C$ is added to a vessel containing water at $0^{\circ }C$, then

• A. all of the ice will melt
• B. some ice will melt
• C. no ice will melt
• D. the temperature will decrease further

Answer 1

The correct option is C no ice will melt

Ice will not melt because the temperature of ice is equal to that of water. Since there is no difference in temperature, so heat exchange takes place, no melting will take place. As for melting heat is required; there is no substance which will release the heat.
