A 500 g sample of water at 50 C is mixed with another 500 g Sample of water at 70 C. What is the final temperature of the mixture?

So im guessing your using the phase change equation which is Q=ML
Heat trasnfer= Mass x latent

I might be wrong though.

Sounds like a temperature equalibrium problem..

What is the specific heat of water in this case?

dtan5457 · Answer

Actually, since there are the same, you don't even need it. You don't need mass either.

Put the hotter substance on the left.

(70-tfinal)=(tfinal-50)

just solve for t final like this is algebra.

To be honest im quite confused on solving for tfinal

dtan5457 · Answer

70-x=x-50

does that make it easier
