The collisions between the gas molecule and the wall are elastic. The intermolecular force between the gas molecules is stronger when the specific volume is smaller. Most substances are approaching ideal gas behaviour while the pressure is high. Which of the following is TRUE for Lee Keslar simple fluid? At temperature close to critical temperature, it behaves as an ideal gas. If oxygen and nitrogen are assumed as Lee Keslar simple fluid, at critical point, the enthalpy of departure of nitrogen is lower than oxygen. For temperature higher than critical temperature, the compressibility factor decreases with the increase of pressure. ✓ At pressure less than 1% of critical pressure, the change of enthalpy can be evaluated by integrating the specific heat with respect to the temperature. At pressure less than 1% of critical pressure, the change of entropy is approximately zero. EME2146 APPLIED THERMODYNAMICS Which of the following is TRUE for a steady state and steady flow open thermodynamic system? The system is adiabatic or isentropic. Most substances are approaching ideal gas behaviour while the temperature is low. The gas molecule is assumed as a point and has zero volume. Which of the following is TRUE for a close thermodynamic system? The volume of the system remains constant for any change of state. The work done on the system is equivalent to the decrease of internal energy of the system if the system is thermally insulated. The heat transfer into the system is equivalent to the increase of internal energy of the system if the system is held at constant pressure. The mass remains constant even reaction occurs in the system. Entropy will never decrease for an isolated system. D. Helmholtz Trimester 2, 2022/2023 The system must be a single phase system. The inflow mass flow rate is equal to the outflow mass flow rate. The rate of increase of internal energy between the inflow and outflow is equal to the rate of net energy transfer into the system. The rate of increase of enthalpy between the inflow and outflow is equal to the rate of net energy transfer into the system. 6. Which of the following quantity is equal to the specific heat ratio? A.
