what is the relationship between enthalpy of sublimation fusion and vaporization?

$\star{\pink{\bold{\underline{\underline{answer : - }}}}}$

• The enthalpy change that accompanies the conversion of one mole of solid directly into its vapour at constant temperature is called as enthalpy of sublimation.

∆sub (H) ──￫ ∆fus (H) +∆vap (H)

$\green{\bold{\underline{sublimation \: fusion : - }}}$

sublimation is a chemical process that involve the direct conversion of gas to solid on heating and solid to gas on cooling without going through a liquid stage. Fusion is the process in which the change of solid state to liquid state is called fusion it is also known as melting.

$\orange{\bold{\underline{vaporization : - }}}$

Vaporization, conversion of a substance from the liquid or solid phase into the gaseous (vapour) phase. If conditions allow the formation of vapour bubbles within a liquid, the vaporization process is called boiling. Direct conversion from solid to vapour is called sublimation.
