Identify the choice that best answers the question A Closed

Identify the choice that best answers the question. A Closed System is one in which: The volume remains constant No energy crosses the boundary No mass crosses the boundary No energy or mass crosses the boundary In normal conditions (1 atm. 300K), 1 m^3 of liquid water weighs: 1 kg 10 kg 100 kg 1000 kg The following are extensive properties: Mass, volume, pressure Volume, energy, mass Energy, mass, temperature Mass, density, volume In equilibrium, for a liquid vapor system, if the pressure is higher than the saturation pressure at the system temperature, the system is. liquid vapor a mixture of liquid and vapor undetermined

Solution

1. C 2. D pv= mrt. 3. B

Closed system means controlled mass

Extensive property depends on mass of the system
