a 1.0 kg sample of metal with a specific heat of 0.50KJ/kgCis heated to 100.0C and then placed in a 50.0g sample of water at 20.0C. What is the final temperature of the metal and the water?

I can't figure this out. Is the answer room temperature???

No. The sum of heats gained is zero.

heat gained by water + heat gained my metal=0

mw*cw*(Tf-20)+mm*cm*(Tf-100)=0

solve for Tf.
