I am going to define these things as I understand them. Please correct/refine them as necessary.
A bomb calorimeter is a small volume capsule within a tank of water. A reaction is carried out within this small capsule and the heat evolved is transferred to the water and the heat change of the water is measured. But what about the pressure change within the small capsule? Isn't that a representation of heat as well? Is enthalpy the heat change only? Or does it somehow take into account the pressure as well?
