# Physics Question Help watch

1. In class we did an experiment where we had to transfer an 100g mass from hot water to cold water and take measurements in order to work out the specific heat capacity of the mass (with "Q=mcΔθ"). We had to repeat the experiment with two different starting temperatures for the hot water and the specific heat capacity of the 100g mass came out as a different value which led to the question which was set as homework (which I have no idea how to answer).

Why wasn't the specific heat capacity the same for both starting temperatures? State 3 reasons.

What ideas do you have? Are you aware specific heat capacity changes with temperature?
