The amount of heat required to raise a unit mass of substance through a unit rise in temperature is called as.

The amount of heat required to raise a unit mass of substance through a unit rise in temperature is called as

a. heat capacity of a substance
b. specific heat of a substance
c. latent heat of a substance
d. none of the above

Correct Answer : b. specific heat of a substance

Explanation :

Specific heat of the substance is defined as the amount of heat required to raise a unit mass of substance through a unit rise in temperature. The symbol used for specific heat is 'c'.

c = Q / (m . Δt) J/kg K

Where Q is the amount of heat in J, m is the mass of substance in kg, t is the temperature in K.
For gases, if the process is at constant pressure then specific heat is

c_p. If the process is at constant volume, then it is c_v.

The product of mass (m) of the substance and specific heat (c) is heat capacity. The capital letters, C , C_p , C_p are used for heat capacity.
