Would it be more efficient to warm your bed on a cold night with a hot water bottle that contains 1kg of water at 50c with a 1kg gold bar at 50c? Why?

• science -

Which has more stored heat? Ans: the one with the highest heat capacity.

• science -

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

• science -

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
