A 10-kg piece of aluminum (which has a specific heat of 900 J/kg×°C) is warmed so that its temperature increases by 5.0 C°. How much heat was transferred into it?
Given the info provided, this is a simple Q=mc(delta)T question. Simply plug and chug.
c=specific heat = 900j/kgxC
(delta)T= 5 C
The answer should be 4.5x10^4 J
