Question
The specific heat capacity of a substance A is 3,800 Jkg `"^(–1)K^(–1)` and that of a substance B is 400 `"^(–1)K^(–1)`. Which of the two substances is a good conductor of heat ? Give a reason for your answer.
Solution
SA = 3,800 Jkg `"^(–1)K^(–1)`
SA = 400 Jkg `"^(–1)K^(–1)`
B is a good conductor.
∴ The specific heat is less, i.e. amount of heat required to raise the temperature of unit mass of a substance by 1°C is less.
