(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] Find Change in Temperature

1. The problem statement, all variables and given/known data

An electric drill bores through a .100 kg piece of copper in 30 s. Find the increase in the temperature of the copper if the drill operates at 40 W. Assume that the drill does not increase in temperature.

2. Relevant equations

Q = mcT

3. The attempt at a solution

Can someone check to see if I'm doing this right?

I know the P = W/T so I would have to multiply T by Watts. I get 1200 J. I then rearrange Q = mcT to T = Q / mc. T = 31.01 degrees C.
