A 0.75 kg mass of copper changes temperature from 145.0 C to 46.0 C. How much heat was exchanged in Joules? Did the heat flow into the copper or out of the copper?

Answer 1

Q = .75 * specific heat of copper* (145-46)

the copper lost heat to get cooler !

Answer 2

so you just multiply those all together?

Answer 3

Yes. Look up the specific heat capacity for copper in Joules/ Kg deg K in your text

Answer 4

thanks
