Amount of heat, required to raise the temperature of a substance by a certain amount, depends on the properties of the substance and this amount of heat varies from substance to substance. Specific heat is essentially a measure of how thermally insensitive a substance is to the addition of energy. Specific Heat Calculator will help us to calculate the specific heat of different substances.

Specific heat c of a substance is defined as the heat capacity of the substance per unit mass of the substance.

Specific Heat Formula
Specific Heat of the substance is

c = $\frac{Q}{m \Delta{T}}$

Where
c- Specific heat of the substances
Q- The energy given to the substance
m- Mass of the substances
$\Delta$T- Change in the temperature of the substance.

 

How to Calculate Specific Heat?

Step 1 :  

Specific Heat Formula:


Specific Heat(c) = $\frac{Q}{m \Delta{T}}$


Quantity of Heat Needed(Q) = c $\times$ m $\times$ $\Delta{T}$


Mass of the Substance(m) = $\frac{Q}{c \Delta{T}}$


Change in the Temperature($\Delta{T}$) = $\frac{Q}{m \times c}$

Where
c- Specific heat of the substances
Q- The energy given to the substance
m- Mass of the substances
$\Delta$T- Change in the temperature of the substance.



Step 2 :  

State the equation you plan to use and plug in the values.

  1. Calculate the specific heat of a substance which absorbs 4.6 joules of heat when its mass of 2.0 kg increases with respect to the change in temperature of 60$^{\circ}$C?


    Step 1 :  

    Given that:


    Quantity of Heat Needed(Q) = 4.6 joules


    Mass of the substances(m) = 2.0 kg


    Change in Temperature($\Delta{T}$)  = 60$^{\circ}$C


    Specific Heat(c) = ?



    Step 2 :  

    We know that:


    Specific Heat(c) = $\frac{Q}{m \Delta{T}}$


    Specific Heat(c) = $\frac{4.6}{2.0 \times 60}$  


    Specific Heat(c) = 0.0383333333 J/kg.$^{\circ}$C



    Answer  :  

    Specific Heat(c) = 0.0383 J/kg.$^{\circ}$C



  2. Calculate the amount of heat required for a substance of mass 3.0kg, whose specific heat is 0.632 J/kg.$^{\circ}$C during the temperature difference of 50$^{\circ}$C?


    Step 1 :  

    Given that:


    Specific Heat(c) = 0.632 J/kg.$^{\circ}$C


    Mass of the substances(m) = 3.0 kg


    Change in Temperature($\Delta{T}$)  = 50$^{\circ}$C


    Quantity of Heat Needed(Q) = ?



    Step 2 :  

    We know that:


    Quantity of Heat Needed(Q) = c $\times$ m $\times$ $\Delta{T}$


    Quantity of Heat Needed(Q) = 0.632 $\times$ 3.0 $\times$ 50


    Quantity of Heat Needed(Q) = 94.8 joules



    Answer  :  

    Quantity of Heat Needed(Q) = 94.8 joules
