Difference between Heat and Specific Heat Capacity

HEAT CAPACITY

HEAT CAPACITY SPECIFIC

Definition

It is defined as the quantity of heat required to produce unit temperature change.It is the quantity of heat to change the

the temperature of a unit mass of a substance by

one degree Celcius (0C).

Unit

Its S.I unit is J/k.Its S.I unit is J/kg K.

Value

Its value depe1ids on the mass and nature of the substance.Its value depends on the nature of the

substance.

 

HEAT CAPACITY

Take a number of samples of different amounts of the same substance (say, copper) and heat them through the same range of temperature. It will be found that the heat required for this purpose is different for different samples. If Q is the amount of heat needed to raise the temperature of a sample through T, then the ratio is known as the heat capacity of the sample (hot of the Substance). It is denoted by C so that

 

Unit

In the system international the unit of heat capacity is JK-1.

 

SPECIFIC HEAT CAPACITY

Definition

The quantity of heat required to change temperature fone kg mass of a substance by one

Kelvin Is called specific heat

EXPLANATION

  • Take equal amounts of different substances, for example, copper, iron, and water.
  • Heat them for a given interval of time under the same flame so that they all absorb the same amount of heat energy from the source.
