Explanation has to be given for the observation- “A liquid gets cooler when it evaporates from an insulated container”. Concept introduction: The phenomenon of evaporation of liquid is transition from “ liquid phase ” to “ vapo r phase ”. Almost all the liquids have the tendency to evaporate either spontaneously at room temperature without the effect of “ external energy ” or in the presence of external energy like heat etc. Since evaporation occurs by the process of absorbing heat from the surroundings, it is an endothermic process. Insulation is a process in which there is no transfer of heat or any other form of energy from one body to the other or surroundings.
