Ethanol + H 2 O longrightarrow A non-ideal solution, which shows positive deviation from Raoult's law, thus Δ H=+ ve, ie, reaction is endothermic and Δ V=+ ve, ie, volume rises.

Absorption of heat and contraction of volume

Liberation of heat and contraction of volume

Absorption of heat and increase in volume

Liberation of heat and increase in volume

Ethanol $+ H_{2} O ⟶$ A non-ideal solution, which shows positive deviation from Raoult's law, thus $Δ H = +$ ve, ie, reaction is endothermic and $Δ V = +$ ve, ie, volume rises.
