Vedclass · Answer

(A) physical change is a change in which no new substance is formed and the chemical composition remains the same.$A$. Combustion of $LPG$ is a chemical change because it involves a chemical reaction with oxygen to produce new substances like carbon dioxide and water,releasing energy.$B$. Melting of ice is a physical change as it only involves a change in the state of water from solid to liquid.$C$. Dissolution of salt in water is a physical change because the salt can be recovered by evaporation,and no new chemical substance is formed.$D$. Boiling of water is a physical change as it only involves a change in the state of water from liquid to gas.Therefore,the combustion of $LPG$ is not a physical change.
