The correct answer is C): Amount of heat absorbed or released is doubled if quantity is doubled. If a different substance with half the specific heat capacity is used, the amount of heat absorbed or released is cut in half.
Let's see why. the amount of heat Q absorbed or released is given by
[tex]Q= m C_s \Delta T[/tex]
where m is the mass (so, the quantity of the substance), Cs is the specific heat of the substance and [tex]\Delta T[/tex] is the variation of temperature.
We can see from this formula that Q is directly proportional to both m and Cs. Therefore:
- If the amount of heat Q is doubled, m is also doubled
- If the specifice heat of the new substance is half of the original one, then Q is also cut in half.
