The specific heat capacity of a material is the amount of energy (Q) needed to raise 1 kg of a material through a temperature change of 1 kelvin. Latent heat is taken in / or given out when a material changes state e.g. solid to liquid or liquid to gas.

Hey Mate
Specific heat: = energy required to change a unit mass of a material by 1°C. Units: energy per unit mass per degree.Latent heat = energy required to change the state (gas, liquid, solid) of a unit mass of material. Units: energy per unit mass.
Both specific heat and latent heat are properties of a given material. In other words, every time the material is heated/cooled, no matter how quickly or by what heating process, the same amount of heat is transferred to reach the same state.
hope it helps
