When we are warming ammonium chloride with sodium hydroxide in a test tube, there is an exchange of heat as well as the mass between the system and surrounding due to an open test tube or test tube without a cap. Mass is transferred from the open end of the test tube due to evaporation. Also, heat is being exchanged through the walls of the test tube.

Hence, the option number (3) is correct.
