Potential Energy - Enthalpy

The second form of energy studied in chemistry is called Potential energy. 

Potential energy is commonly called Enthalpy in the chemistry world.

Can we measure potential energy like we measure kinetic energy? 

Oh, actually Potential energy is equal to thermal energy, however we cannot measure by using the thermal equation, because it does not require temperature change.

Enthalpy energy is stored in the chemical bonds of molecules within a substance. When these bonds are broken or formed there will be a change in the total enthalpy of the substance. 

Therefore we can measure enthalpy change by using the equation:

 ΔH = nΔHm

Where ΔH is Enthalpy change (kJ), n (moles) and ΔHm (molar enthalpy).

Whoa whoa, what the heck is molar enthalpy?

Molar enthalpy is the change in the enthalpy when on per mole of substance undergoes a process.
