Whats the question?

anonymous · Answer

sorry, if the pot was made out of aluminum and it weighed 100 g, how much heat energy was required to heat the pot (specific heat capacity of aluminum is 875 J kg-1 K-1)?

anonymous · Answer

So now you are heating water + aluminium from 20 to 100 degree
Heat required by aluminium= mCT=0.1*875*80=7000J=7kJ.
The other data are irrelevant.
