Homework Help: Physics - Heat Transfer

Posted by Brenda on Thursday, December 6, 2012 at 10:40am.

I am trying to calculate heat transfer between two objects. The units are as follows:

m1: 100 g
t1: 10 degrees C
spec heat 1: 1.00 cal/g degree C

m2: 200 g
t2: 90 degrees C
spec heat 2: 0.2 cal/gm degree C

I set Q1 = Q2
m1 x spec heat 1 x delta T1 = m2 x spec heat 2 x delta T2 and solved for T final where Tfinal 1 = Tfinal 2.

My numbers aren't working out.
