Morphology
heat + of + dissociation
The phrase denotes the heat associated with the process of dissociation, so its meaning is directly derived from combining 'heat' (energy transfer) with 'dissociation' (splitting of molecules). The 'heat of X' compositional pattern is common in scientific register and across languages, so a learner who knows the constituents can infer the intended meaning.
Etymology
Heat of dissociation gives a simple picture: heat is the warm energy and dissociation is when a substance is broken into parts. So it means the amount of 'heat' needed to 'break into parts', for example to separate molecules into atoms or ions.
