A note on the variation of specific heats in ideal gases Most diatomic
... Most diatomic gases such as nitrogen (N2) and oxygen (O2) at or near room temperature have specific heats (cv and cp) that are almost constant. However, as the temperature (T) rises above about 700 K, the specific heat begins to rise. Because the relation c p (T ) − cv (T ) = R ...

... • Gases at low pressures behave as ideal gases and obey the relation Pv = RT. The properties of ideal gases are relatively easy to evaluate since the properties u, h, cv, and cp depend on temperature only. • At high pressures, however, gases deviate considerably from idealgas behavior, and it become ...

Write-up for Thermodynamics and Carnot Engine Laboratory Exercise
... A Carnot engine cycle is a clockwise thermodynamic cycle made up of two isothermal and two adiabatic processes. Equipped with the above information as well as the First Law of Thermodynamics you have Q = Eint + W Q is the heat exchange from/to the gas and W is the work done by the gas. You are then ...
