Define (i) Sublimation (ii) Triple point.
Answers
(I)Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state. ... Sublimation has also been used as a generic term to describe a solid-to-gas transition (sublimation) followed by a gas-to-solid transition (deposition).
(ii) In thermodynamics, the triple point of a substance is the temperature and pressure at which the three phases of that substance coexist in thermodynamic equilibrium. It is that temperature and pressure at which the sublimation curve, fusion curve and the vaporisation curve meet.
Sublimation:- Sublimation is the process by which a substance changes from solid state directly to vapour state.
Triple point:- the triple point of a substance is the temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium
