The specific heat capacity of a substance A is 3,800

The specific heat capacity of a substance A is 3,800 J kg^-1 K^-1 and that of a substance B is 400 J kg^-1 K^-1. Which of the two substances is a good conductor of heat? Give a reason for your answer.

Answer

Substance B is a good conductor of heat.

Because specific heat capacity of B is less than that of A and specific heat capacity is the heat energy required to raise the temperature of 1 kg of a substance by 1°C, so substance B gets heated faster.
