For an ideal gas the ratio of specific heats isCpCv=γ. The gas undergoes a polytropic process PV^(n) = a constant. Find the values of n for which the temperature of the gas increases when it rejects heat to the surrounding.
Determine the effective gas constant, the specific heats, and the specific heat ratio for this mixture. Assume helium and oxygen behave as ideal gases with constant specific heats. Solution a. From Example 12.3 and Eq. (12.23), we find that the partial pressure of oxygen in air at STP is...

Q represent an energy transfer not the heat energy of the system. In addition to the ideal gas law PV = NkT, the quantity PVg is constant for an ideal gas where g = cP/cV, the ratio of molar specific heats. For an ideal gas the work W = (P1V1 - P2V2)/(g - 1)...
thespecific heat ratioor thepolytropic coefficientbecause in a polytropic process, the heat capacities are taken to be independent of temperature. If we prefer to consider a unit mass of gas, thenρ = m/V∝ 1/V, so the adiabatic equation of state can be written in terms of the gas ...
We calculate the specific heat of the ideal gas obeying the generalized exclusion statistics (GES) in the continuum model and the tight binding model numerically. In the continuum model of 3-d space, the specific heat increases with statistical parameter at low temperature whereas it decreases with...

An ideal Otto cycle has a compression ratio of 8. At the beginning of the compression process, air is at 95 kPa and 27 °C, and 750 kJ/kg of heat is transferred to air during the constant-volume heat-addition process. Taking into account the variation of specific heats with temperature...
