It is common to introduce an ideal gas as one which obeys the equation of state p ν = RT . This is often represented as a 'semi-empirical' fact: the behaviour of the gas approaches this equation as the pressure p tends to zero....
ideal gas n. A gas having particles that have perfectly elastic collisions and negligible volume and intermolecular forces, thus exactly obeying the ideal gas law. No known gas is an ideal gas, but actual gases approximate this behavior at relatively low pressure and high temperature. ...
(General Physics) an equation that equates the product of the pressure and the volume of one mole of a gas to the product of its thermodynamic temperature and the gas constant. The equation is exact for an ideal gas and is a good approximation for real gases at low pressures. Also called...
However, one must remember that all of this is done with reasonable tolerances to the ideal gas definition and ideal gas law equation. This is done over various parameter ranges around standard pressure and temperature. Usually, gases are more likely to behave like an ideal gas and follow the...
Now let us consider an ideal gas as the working substance. For a process at constant pressure with the same temperature change dT, we have dQp= mcpdT. As the internal energy U of a gas depends on temperature only, the value of dU in this process will be the same, i.e., dU = mc...
