Question

1. Calculate the total heat content of 10 kg of ice at -23°C.?

2. How much heat is contained in 100 kg of water at 60.0 °C?

Answer 1

1300 kcal

this is the right answer, i had this question

Answer 2

To solve the problem, we must know the heat capacity of ice and water.

For Cp = 2090 J/kg C

H = mCpT

H = (10 kg) ( 2090 J/ Kg C) ( -23 C)

H = - 480700 J

For water Cp = 4180 j/kg C

H = (100 kg) ( 4180 J/kg C) ( 60 C)

H = 2508000 J
