Question

The amount of energy needed to raise one gram of a substance one degree Celsius is a characteristic property known as

Answer 1

The answer is heat capacity.

Answer 2

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 :

$C=\frac{q}{m\times \Delta T}$

where,

C = specific heat capacity

m = mass of a substance

q = heat required

$\Delta T$ = 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.
