However, analyzing the outputs from our numerical model of an ideal gas, we noticed that the atoms separate during the expansion of the gas into empty space. This separation occurs as a consequence of the distribution of molecules by velocities. Namely, faster molecules will move further away ...
BIf both assertion and reason are true but reason is not the correct explanation of assertion CIf assertion is true but reason is false. DIf both assertion and reason are false.Submit Which of the following is true for an isothermal free expansion of an ideal gas? Aq=0 Bw=0 CΔH=0 ...
Free Expansion:The free expansion is defined as the expansion of a system when the external pressure on the system approaches and equals zero. The work of free expansion is zero also the change in internal energy the zero.Answer and Explanation: ...

or flow in a homogeneous porous medium, induced by an explosion, is treated; approximate formulas valid for the free expansion of the gas bubble in a high‐porosity, high‐permeability medium are developed. These results show that ideal flow is strongly modified in a porous medium; the flow ...
ideal gas law Also found in:Encyclopedia,Wikipedia. n. A physical law describing the relationship of the measurable properties of an ideal gas, where P (pressure) × V (volume) = n (number of moles) × R (the gas constant) × T (temperature in Kelvin). It is derived from a combinati...

Noun1.gas- the state of matter distinguished from the solid and liquid states by: relatively low density and viscosity; relatively great expansion and contraction with changes in pressure and temperature; the ability to diffuse readily; and the spontaneous tendency to become distributed uniformly throu...
Many oil wells produce through a depletion-drive mechanism, also called expansion drive. Here, energy to move fluid through the rock is provided by expansion of the fluids in the reservoir as pressure declines. The remaining reservoir pressure is sustained through the expansion of gas and, to a...
