Question

If the same amount of heat is added to 50.0 g samples of each of the metals which are all at the same temperature, which metal will reach the highest temperature?
Copper 0.385 J/gºC
Magnesium 1.02 J/gºC
Mercury 0.138 J/g °C
Silver 0.237 J/g °C
Lead 0.129 J/gºC
a. Copper
b. Magnesium
c. Mercury
d. Silver
e. Lead

Answer 1

Answer:

e. Lead

Explanation:

Hello,

In this case, since the equation to compute the heat in a heating or a cooling process is:

$Q=mCp(T_2-T_1)$

We can see that the lower the specific heat of the substance, the higher the reached temperature as they are in an inversely proportional relationship. In such a way, we can say that e. Lead will reach the higher temperature if the same heat is added to same mass of the other metals.
