Specific Heat Capacity Table

Specific heat capacity table shows values of specific-heat capacity for some common substances. Some tables also show the specific heat capacity of different substances in different units.

High Specific Heat

Specific heat is defined as amount of energy required to raise the temperature of a unit mass by one degree Celsius. Each element has its particular specific heat. Specific-heat of water is defined as amount of energy required to raise the temperature of one gram water by one degree Celsius. It account for 1 Cal/ gram *C for water. Hence water has high value of specific heat. The high specific heat of water gives it some unique physical properties. Water also serves as temperature regulator in living organisms due to its high specific heat. As it need a high amount of energy (1 Cal/ gram) to raise the temperature of water which is normally not available under room temperature. Hence water serves to maintain the body temperature to a almost constant value.

Calculating Specific Heat

Specific heat is the amount of energy required to raise the temperature of one unit mass of a substance by one degree Celsius. It is expressed by following equation:

C=Q / (m* �� t)

Here C= specific heat

Q= amount of energy added

m=mass of substance

�� t= temperature of substance before adding heat- temperature of substance after adding heat energy.

Calorimetry Equation:

Calorimetry is a specific device where the chemical reaction and physical processes are carried out. The device serve as isolated system as the calorimetry walls made up of insulated materials, hence there is no energy exchange with surroundings.

The equations of calorimetry depends on its types, bomb calorimetry, classical calorimetry, etc.

The name bomb calorimetry is given to the constant volume calorimetry.

We will look for the equation of the bomb calorimetry;

Qreaction = -(Qwater + Qbomb)

where;

q is the heat flow

What is Specific Heat Capacity

Specifc heat capacity is the amount of energy required to raise the temperature of a unit mass of any substance or gas by one degree Celsius. Here energy should be used in raising temperature of the substance only, not in the phase change. Specifc heat capacity can be measured at constant volume and constant pressure.

pecific heat capacity of a substance at constant pressure is expressed as

Cp= (δh/δT)p; and

Specific heat capacity of a substance at constant volume is expressed as following formula:

Cv=(δU/δT)v.
