energetics question
« on: May 08, 2006, 06:26:02 PM »
Could someone please help me with this question. Thanks

Explain what is wrong with this statement: If you add 100g of Copper at room temperature (20°C) to 100g of water at 60°C and stir them, the final temperature of the mixture will be 40°C.

the heat capacity of water is different than the heat capacity of copper, if the substances were both water, one at 273K and one at 298K then it would be the average of the two.
