What is Thermodynamics?An open system can exchange both matter and energy that is present with its surroundings. A closed system, on the opposite hand, can exchange only energy with its surroundings, not matter. An isolated system is one that can't exchange either matter or energy with its surroundings. SOLUTION (a) The mass balance equation will yield the rate of change in mass of this open system as it changes from state 1 (m = 1000 kg) to state 2 (m = 500 kg).
