Which has more stored heat? Ans: the one with the highest heat capacity.
dont understand the answer, the question does not say which one has the most stored heat, just the amount of each and temp of each
The answer still is the same. Calcualte the heat stored in the 1 kg water and 1 kg gold and you will know which can produce the most heat to the bed.
q = mass x specific heat x T
q = mass x specific heat x T
