Question

Specific heat capacity of substance A is 3.8 J g^-1 K^-1whereas the specific heat capacity of substance B is 0.4 J g^-1 K^-1. Which of the two is a good conductor of heat? How is one led to this conclusion?

Answer 1

Specific heat capacity ‘A’ 3.8 J/g/K. Specific heat capacity ‘B’ 0.4 J/g/K
‘B’ is a good conductor of heat.
Since specific heat capacity is the energy required to raise the temp. of 1 g of a substance 1°C. So less heat energy passes through the substance.
