The specific heat capacity of copper is three times the specific heat capacity of lead.Equal masses of copper and lead are heated from room temperature to the temperature of boiling water.To achieve this,the amount of heat added to the copper is ___________ the amount of heat added to the lead.
A)1/9
B)1/3
C)equal to
D)3 times
E)9 times

Question

Quizplus · Accepted Answer

The amount of heat added (Q) is given by Q = mcΔT, where m is mass, c is specific heat capacity, and ΔT is the change in temperature. Since the specific heat capacity of copper is three times that of lead, and the masses and temperature changes are the same, the heat added to copper is three times that added to lead.

The Specific Heat Capacity of Copper Is Three Times the Specific
