Is Evaporation a Physical Change or Chemical Change
Even though the physical state changed the chemical properties were the same. Particularly the evaporation model proposed by Haelssig et al. Physical Vs Chemical Changes Chemical Changes Solubility Physical Change Has been extended to evaporating liquidgas systems wherein the liquid phase comprises two components n-heptane and n-decane and the gas phase comprises four components or chemical species viz. . Vapours of n-heptane and n-decane N 2 and O 2. Latent heat can be understood as energy in hidden form which is supplied or extracted to change the state of a substance without changing its. On the other hand a chemical change would build or break the chemical bonds in the water H 2 O molecules. No matter what physical state it was in it was always water. Latent heat also known as latent energy or heat of transformation is energy released or absorbed by a body or a thermodynamic system during a constant-temperature process...
