Enthalpy of sublimation of a substance is equal to (a) enthalpy of fusion + enthalpy of vaporisation (b) enthalpy of fusion (c) enthalpy of vaporisation (d) twice the enthalpy of vaporisation
when concentrated acid is added to water identify whether the process is exothermic or endothermic ??
Latent heat of fusion (or vaporisation) is the heat energy that is absorbed by solid (or liquid) without showing any rise in temperature.
