thermochemistry problem

[murda_jr427]

could someone help me with this problem?

The specific heat of copper metal is .38 J/g-k. Assume you had a 75 g cube of copper at 25 celcius.
what would the final temperature of the copper be (in celsius) if it absorbed 150 J of heat?



here's another one.

how much energy (in Kj) is required to raise the temperature of 0.1 g of water from 20 degrees celsius to 20.15 degrees celsius?

First answer is 5.13 K rise- so 30.13 celsius

second answer is 0.0628
