This type of problem involves several calculations: A phase change (in this case from solid to water (heat of fusion) and the temperature increase.

First the phase change (heat of fusion) 79.7 cal/gram (334 kJ/kg) AND The change in temperature (specific heat) 1 cal/gram/degree change = 35 cal/gram (35 degree change)

79.7 + 35 = 114.7 cal/gram To get your final answer: Multiply by the 50 grams to get 5,735 calories
