heat + of + vaporization
The phrase is a straightforward compositional noun phrase: 'heat' (energy) related to the process named by 'vaporization' (turning a liquid into vapor), so the meaning ‘the heat associated with vaporization’ is directly derivable from the parts. It follows a regular English 'X of Y' technical naming pattern that is cross‑linguistically common, so a learner who knows the constituents would understand the term.
Etymology
Heat of vaporization comes from its literal parts: heat (the energy you give) and vaporization (the act of turning a liquid into a gas). Think of boiling water: you keep adding heat but the temperature stays the same until the water becomes gas. So, the phrase means the exact amount of heat needed to 'vaporize' a liquid.
