Specific heat is the amount of heat required to raise the temperature of a substance a certain amount. Latent heat is the amount of heat released during a change of state, i.e. the boiling of water or the melting of ice.
Specific heat and latent heat.
What is the difference between specific heat and latent heat?
Specific latent heat is the amount of heat required to raise the temperature of a body of mass 1kg by 1k(kelvin).
while latent heat is the amount of heat released or absorbed by a body when it changes its state. there is no change in temperature.
This is the heat released in a Change of State, ie steam to water for example, or in reverse the heat required to evaporate water which is already at boiling point into water vapour. It also appears in many other substances during a change of state, for example when liquid wax solidifies, the latent heat is released.
Specific Heat mans the amount of heat required to raise the temperature of a substance by a certain amount (or of course the heat it releases in cooling the same amount). It can be expressed in various units, depending which is suitable for the case being studied.
Specific heat capacity (equation Q=mcΔT) is the measure of the energy required to rise 1kg of a substance by 1 0c/kg/j
Whereas, specific latent heat (equation Q=mL) is the amount of energy needed to change to the state of a substance either from solid to liquid, liquid to gas without changing its temperature
Specific heat is used to raise one degree of 1 kg of a body
Latent heat is the amount of heat released when body changes state
