Answer:
Three times
Explanation:
The amount of heat added to a substance when its temperature is increased from T_1 to T_2 is given by
[tex]Q=mc(T_2-T_1)[/tex]
c= specific heat capacity
m= mass of the substance
⇒Q∝c
that is if c is increased three times the amount of heat added is also increased three times. Therefore, the amount of heat added to the copper is three times the heat added to lead.
