1.	which system tranfer energy to and from its surroundings by the process of heating or coolong and the process if mechanical work?
Answer» A REACTION or process in which HEAT is TRANSFERRED from a system to its surroundings is exothermic. A reaction or process in which heat is transferred to a system from its surroundings is endothermic. The FIRST law of thermodynamics states that the energy of the universe is CONSTANT
