## Homework Statement

A copper calorimeter can with mass 0.100 kg contains 0.160 kg of water and 0.018 kg of ice in thermal equilibrium at atmospheric pressure.

## Homework Equations

If 0.750 kg of lead at a temperature of 255 C is dropped into the calorimeter can, what is the final temperature? Assume that no heat is lost to the surroundings.

## The Attempt at a Solution

mc[tex]\Delta[/tex]t

_{copper}+mc[tex]\Delta[/tex]t

_{ice+water}+mL(ice)=mc[tex]\Delta[/tex]t

_{lead}
