Answer:
MASS
Explanation:
Formula for heat energy will be;
Q = mcΔt
Where;
m is mass
c is specific heat capacity
ΔT is change in temperature
Now, since both substances are copper, it means they will have the same specific heat capacities.
Thus, from the formula given earlier, it is seen that the mass is inversely proportional to the temperature change.
This means that the smaller the mass, the greater the temperature change.
Thus, the 3 g sample of copper will experience a greater temperature die to its smaller mass
