How much heat, in kcal, does it take to melt a 500 gram block of ice originally at 0.0 C until it is liquid water at 25.0 C?
Please show work. Thank you!
Homework Answers
At first we have to calculate the amount of heat required to melt the ice into water. Then we have to raise the temperature of the water to 25 °C from 0°C. For this we need to supply heat. So total heat is the sum of this two amount of heat we needed to supply.
The answer is given below.
