Homework Problem 8.41

Postby Anmol Dhaliwal 2C » Sat Jan 21, 2017 9:17 pm

Can someone explain why in the solutions manual, 50g is added twice when trying to find the heat of the ice cube (once when converted into moles and then again when multiplied to numbers 4.184 J*C^(-1)*g^(-1)?

At 0 degrees Celsius, there is a phase change because it has a mixture of ice and water. Therefore we must add that to the temperature change at 0 Celsius.

It takes energy to melt the ice
