So it's just the sign that changes . Thanks very much

Yes my physics book doesn't give those values though so I hadn't even thought I could use those.

So since the steam is undergoing a phase change to become water. I'm not sure what to multiply the mass for since it isn't fusion or vaporization.

The steam should become water since water boils at 100C. So it should just be common sense? Or is there a calculation I should be making?

Homework Statement In each case, the following are mixed in a perfect calorimeter with no heat lost or gained from the system. Find the final temp in each case. 12.5 g of steam at 100C with 344 g of water at 22.2C. Homework Equations Q=Mc(Tfinal-Tinitial) M is the mass in kg C...
