SSC MTS EXAM

Detailed explanation-1: -Vaporization: the substance changes from a liquid to a gas. Sublimation: the substance changes directly from a solid to a gas without going through the liquid phase. Deposition: the substance changes directly from a gas to a solid without going through the liquid phase.

Detailed explanation-2: -Sublimation is a type of phase change that takes place when a solid turns directly into a gas, skipping the liquid phase. The opposite of sublimation is vapour deposition. The term “sublimation” only applies to a physical change of state and not to the transformation of a solid into a gas during a chemical reaction.

Detailed explanation-3: -The conversion of a solid to a liquid is called fusion (or melting). The energy required to melt 1 mol of a substance is its enthalpy of fusion (Hfus). The energy change required to vaporize 1 mol of a substance is the enthalpy of vaporization (Hvap).

Detailed explanation-4: -vaporization, conversion of a substance from the liquid or solid phase into the gaseous (vapour) phase.
