The heat required to raise the temperature of body by 1 K is called

  • A.Specific heat
  • B.Thermal capacity
  • C.Water equivalent
  • D.None of the above

Answer: B

This is the thermal capacity, or heat capacity, of the body.

\[C=\frac{Q}{\Delta T}\] measured in \(\mathrm{J\,K^{-1}}\). It depends on the mass of the particular body. Specific heat is the heat needed per unit mass for the same rise, and is a property of the substance rather than of the object.
