Answer : The amount of energy needed to raise one gram of a substance one degree Celsius is a characteristic property known as, Specific heat capacity.
Explanation:
Heat capacity : It is defined as the heat required to raise the temperature by one degree.
Specific heat capacity : It is defined as the amount of heat required by one gram of a substance to raise its temperature by one degree Celsius.
The heat required to change the temperature of a substance is related to heat capacity of the substance by the expression as :
where,
C = specific heat capacity
m = mass of a substance
q = heat required
= change in temperature of substance
Hence, the amount of energy needed to raise one gram of a substance one degree Celsius is a characteristic property known as, Specific heat capacity.
