Question

What is the mass of a piece of copper when 3000 J of heat is applied, causing a 45 °C increase in temperature, if the `C_p` of copper is .38452 J/g °C?

Answer 1

I found `173.4g`

Explanation:

I would use the relationship describing heat exchanged `Q` as:
`Q=mc_pDeltaT`
With our data:
`3000=m*0.38452*45`
Rearranging:
`m=(3000)/(0.38452*45)=173.37~~173.4g`
