Heat Transfer and Insulated Thermos

Show ALL your work, including the equations used to solve the problems.

An insulated Thermos contains 13cm^3 of hot coffee, at a temperature of 80.0ºC. You put in a 12.0-g ice cube at its melting point to cool the coffee. By how many degrees has your coffee cooled once the ice has melted? Treat the coffee as though it were pure water and neglect energy transfers with the environment.

This is a tough concept for students to understand early on.

Heat lost = Heat gained

Heat lost by the hot coffee = heat gained by the ice....

We can assume that the ice wll completely melt and turn into water.

What you need to provide to complete this answer would be the constants...

We need the heat of fusion of ice (amount of heat required to melt 1 g of ...
