Earth Bomb Calorimeter Water Bottle Ice Pack Refrigerator Battery IC Engine Earth Earth is one of the major closed system example. 2nd example is water heated in closed vessel 3 Here only heat energy can pass in & out of vessel. A closed system has no mass transfer in/out of the system, but can have energy transfer (heat and/or work) in/out of the system. Unlike an open system, a closed system is therefore only permeable to work and heat and impermeable to matter. In chemistry, a closed system is one in which neither reactants nor products can enter or escape, yet which allows energy transfer (heat and light). Related Articles The exergy of a closed thermodynamic system, or the non-flow exergy, can be expressed as follows:(2.28)Exnonflow=Exphysical,nonflow+Exkinetic+Expotential+Exchemicalwhere Expotential is equal to potential energy, Exkinetic is equal to kinetic energy, Exchemical is equal
