An experiment involved in pouring 150g of heated copper into a 375 g aluminum cup containing 200g of water at 25 deg C. The mixture reached 28 deg C. What was the initial temp of the copper?
Is this Thermal equiliabrium?? mc delta T = mc delta T, but I have 3 items.
How do I compare 3 things?? Or do I do water to the cup and the copper to the cup??
Help if you can, thanks.
