regardless here was a question from my final:

[This is a relatively simple question, assuming once the two rooms reach equilibrium the heat transfer will cease. For this I was asked to find Q and Delta "T", which in this case represents rate of heat transfer and final temperature. The equation I used is derived from Q=M(c)delta T.]

A 1kg piece of aluminum metal at 100 degrees Celsius is placed in 5 liters of water at 25 degrees Celsius, determine the final temperature. Cp-water=4184 J/kg◦C Cp-Al=900J/kg◦C
