another temp prob
heres another one that my books getting me stumped on:
A 34.4 g of water at 65 ?C is mixed with 64.3 g of water at 25 ?C. Calculate the final temperature of the mixture.
it looks so easy but i can't seem to figure it out. do you just subtract the 65 from the 25 to get the temp change? if so then what about the g of water?
please help with this one and the one i sent before soon :? i need to understand these concepts fast.
thank you in advance.
