What will the final temperature be?

Question

If you put an 18g ice cube at 0C in 500g of water at 20C, what will the final temperature of the water be after the ice cube melts?

Answer 1

You still need the specific heats of the ice and water. Refer to tables or data given by your teacher.

Then, use the formula Qi = mC(Tf - Ti) for ice note expect Tf >Ti because melting
also for liquid water Qw = mC(Ti-Tf) note this is cooling

m= mass
C = Specific heat
T = temperature

Then equate the 2 equations together because heat lost = heat gained. Everything is given Ti, m of ice and water, initial temperatures, constants for specific heat. thus you can simply substitute and solve for Tf = final temperature
