ideal gas law the equation of state for simple gases: pressure = (k × density × temperature)/(molecular weight of the gas). inertia the property of an object describing its tendency to stay at the same velocity (or at rest) unless a force acts on it.

Ideal gas law
The ideal gas law is the equation of state of a hypothetical ideal gas, first stated by Beno?t Paul ?mile Clapeyron in 1834.

ideal gas law - (n.)
The volume of a gas is proportional to the amount of gas and its Kelvin temperature and inversely proportional to its pressure.
IDP - (n.) ...

ideal gas law -- a law relating the pressure, density, and temperature of a gas. This law states that the pressure is proportional to the density times the temperature. Also called the perfect gas law.

Ideal Gas Law - The equation of state for a low-density gas in which pressure is proportional to the product of density and temperature
Igneous Rock - A rock formed by solidification of molten material ...

ideal gas laws = gas laws. ideal nozzle The nozzle of an ideal rocket, or a nozzle designed according to the ideal gas laws. ideal rocket A theoretical rocket postulated for parameters that are corrected in practice.

Further manipulation using the differential version of the ideal gas law, the previous equation, and assuming constant pressure, one finds dQ = C_{P} dT-V dP.
For an adiabatic process dQ=0 and recalling gamma = frac{C_{P}}{C_{V}}, one finds ...

This type of assumption is useful for making calculations very simple and easy to do. With this assumption, the Ideal gas law can be applied without restriction and many complications that may arise from the Van der Waals forces can be neglected.

The higher the temperature and the more rarefied a gas, the more closely it obeys the ideal gas laws, so the gases in most stars closely approximate ideal gases.

One such reference system is a fixed quantity of gas. Boyle's law indicates that the product of the Pressure and volume (P×V) of a gas is directly proportional to the temperature. This can be expressed by the Ideal gas law as: ...

Van der Waal equation (NASA SP-7, 1965) The best known of the many laws which have been proposed to describe the thermodynamic behavior of real gases and their departures from the ideal gas laws. It states: ...
