Question

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.

Answer 1

Answer:

three times

Explanation:

Heat added is calculated according to the following equation

Q = mcΔT

where Q is the heat added

           c is the specific heat capacity (of lead for the purposes of this question)

           ΔT is the temperature change in Kelvin or degree Celsius

Q1 for heating lead = mc(373K-298K) = 75mc

Q2 for heating copper = m(3c)(373-298) = 225mc = 3(75mc) = 3Q1
