yasaswani1: you need the meaning or reaction

hankeevai: both

yasaswani1: It gets heated up as CaO produces heat energy by the formation of the hydrate the following equation:

CaO + H2O ↔ Ca(OH)2 + 63.7kJ/mol of CaO

Whitewash cures through a reaction with carbon dioxide in the atmosphere to form calcium carbonate in the form of calcite, a reaction known as carbonatation.When the paint initially dries it is uncured and has almost no strength.It takes up to a few days,depending on climate to harder Thus in the given case the walls get a shiny appearence after two days
