Question

What do you understand by the following statements:

The specific heat capacity of lead is 130 Jkg^-1K^-1.

Answer 1

Specific heat capacity is the amount of heat energy required to raise the temperature of unit mass of a substance through 1°C or 1 K. Thus, 130 Jkg^-1K^-1 of heat energy required to raise the temperature of unit mass of lead through 1 K.
