If the heat needed to melt ice is used to heat up the same amount of liquid water how much will be the increase in temperature for the liquid water?

Answer 1

The specific heat of water is 1 cal per gram per degree.

That means, it takes 1 calorie of heat to increase the temperature of 1g of water by 1°C.

In contrast, it takes 80 cal to melt the same amount of ice.

That means, melting takes 80 times more heat than raising temperature by 1°C.
