<span>During
an investigation, a student determines that a copper sample has a
density of 8.10 g/ml. What is the students percent error of the accepted
density for copper is 8.96 g/ml

The correct answer is
<span>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.
In fact, the amount of heat released or absorbed is given by:
</span>
<span>where
m is the mass of the substance
Cs is the specific heat capacity of the material
</span>
is the change in temperature
<span>
We can see that Q is directly proportional to both m (mass, or quantity of the substance) and Cs (specific heat capacity). So if the quantity (m) is doubled, the amount of heat (Q) is doubled as well. Similarly, if the specific heat capacity (Cs) is cut in half, the amount of heat (Q) is cut in half as well.</span>
