No and yes. If the two liquids do not react chemically then its a physical change, called the enthalpy of mixing, heat of mixing, which can be exothermic or endothermic. If the two liquids react then the heat produced would be chemical.

Is separation of 2 liquids by distillation a physical change?
Yes, separation of two liquids by distillation is a physical change. It involves the process of heating a mixture of liquids to vaporize one of the components, and then condensing the vapor back into a liquid form. This process does not involve any chemical reactions or changes in the chemical composition of the substances.
