Chemical QnA #1
What is Specific heat, Latent heat, Sensible heat ?
Answer
Specific heat
The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius
m = Mass of Substance
Cp = specific heat
ΔT = Temperature difference
= T initial - T final
Latent heat
Heat transfer can occur with no temperature change taking place this heat transfer is referred to as latent heat transfer.
Latent heat transfer results in phase change , that is a substance changes from solid to liquid , liquid to solid , liquid to gas or gas to liquid.
Sensible heat
When an object is heated, its temperature rises as heat is added. The increase in heat is called sensible heat. Similarly, when heat is removed from an object and its temperature falls, the heat removed is also called sensible heat.
Heat that causes a change in temperature in an object is called sensible heat .
