# The Specific Heat Capacity of a Substance a is 3,800jkg – 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. - Physics

Short Note

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.
