What is the resulting temperature when a 150g cube of ice at zero degrees celsius is added to 200g of water in a 100g aluminium cup at 30degrees celsius.

Answer 1

Compute the amount of heat necessary to be removed from the Al and liquid H2O to reduce both to 0 C.

If that heat can be absorbed by the melting of less than 150g or less of ice, then the equilibrium temperature is 0 C.

If not, you will have to do some algebra to get the equilibrium temperature, assuming all the ice melts and is heated to the equilibrium temperature.

You will need the latent heat of fusion of ice (80 cal/g) and the specific heat of aluminum (0.213 cal/g*C).

Answer 2

25 degree celsius
