Answer:
lesser time
Explanation:
The latent heat of fusion is defined as the amount of heat required to convert 1 gram of water into 1 gram of ice at constant temperature called melting point.
In this situation only the state of matter is changed, the temperature of the substance remains constant.
A liquid has lower latent heat rather than water, it means it requires lesser amount of heat to fuse it , so it requires lesser amount of time to melt the ice made by this liquid.
So, it requires lesser time.
