Morphology
heat + of + sublimation
The phrase is a straightforward noun phrase combining 'heat' (energy transfer) with 'sublimation' (the phase change from solid to gas), so its meaning — the heat associated with sublimation — is directly derivable from the constituents. Although technical, this compositional pattern ('heat of X') is regular and mirrored in other languages, so a learner who knows the component words would comprehend it.
Etymology
Heat of sublimation starts from the image of a solid turning straight into a gas, like dry ice that makes fog and seems to disappear without melting. Here heat means the energy needed and sublimation means changing from 'solid' to 'vapor' without becoming a 'liquid', so the phrase names the heat needed for that direct change.
