(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A thermos contains 150 cm^{3}of coffee at 85^{o}C. To cool the coffee, you drop two 11g ice cubes into the thermos. The ice cubesare initially at 0^{o}C

and melt completely. What is the final temperature of the coffee? (Treat the coffee as if it were water)

2. Relevant equations

Q_{f}= mL_{fusion}

Q = mcΔT

3. The attempt at a solution

I am trying to help someone with this problem. They have yet to learn about internal energy, so I am a little lost (forgetful) as to how to approach this problem

and explain it so that it makes sense.

How would you approach this problem?

Thanks,

Casey
