Consider a piston cylinder process in air (as an ideal gas with constant specific heats) which goes from state 1 at 1 atm, 300 K to state 2 at: 3 atm and 400K. (use k=1.4, Cp = 1.005 kJ/(kg K), Cv=0.718 kJ/(kg K), R= 0.287 kJ/(kg K)) (these are the same conditions as question 4). What must the heat transfer be (in kJ/kg), if the process takes place without entropy generation and it can be assumed the temperature at system...

The ideal gas law describes the relationship among the volume of an ideal gas (V), its pressure (P), its absolute temperature (T), and number of moles (n): PV=nRT Under standard conditions, the ideal gas law does a good job of approximating these properties for any gas. However, the ideal gas law does not account for all the properties of real gases such as intermolecular attraction and molecular volume, which become more pronounced at low temperatures and high pressures. The van...

Review Constants Periodic Table Air consists mostly of nitrogen (N), with a molecular mass of 28, and oxygen (O2), with a molecular mass of 32. A water molecule (H,O) has molecular mass 18. According to the ideal gas law (N/ V P /KT), dry air at a particular pressure and temperature has the same particle density (number of particles per unit volume) as humidait at the same pressure and temperature. Consequently, humidair, whose low-mass water molecules replace more massive nitrogen...
