Sentences with phrase «gas number density»

Gas number density varied between 102 and 1010 cm - 3, though the total amount of gas in the simulation stayed constant at 105 M ☉.

Hydrogen is an excellent fuel which, due to its high energetic density and zero greenhouse gas emission, is essential in a great number of industrial processes.

The conditions for mechanical equilibrium doesn't depend on whether the gases are ideal or not, although for an ideal gas, the density depends on the temperature so that there are an infinite number of ways one can stack up the gas with a thermal gradient that are all still in mechanical equilibrium.

The result of our theory is that the final distribution of any number of kinds of gas in a vertical vessel is such that the density of each gas at a given height is the same as if all the other gases had been removed, leaving it alone in the vessel.

OTOH, if by this you mean that both gases will have equilibrium densities and partial pressures that more or less exponentially decay, with distinct exponential constants so that the static equilibrium mixture will not end up being perfectly homogeneous over very large vertical distances, especially if one molecule is physically much larger than and more massive than the other, I don't have a quarrel with that (and neither does Dalton), although I would want to work out the numbers.

The molar density of a gas tells you the average number of molecules per cubic metre of the gas.

According to the ideal gas law PV = nRT, additional warmth (increased T) reduces density when P is held constant, namely by increasing V while leaving n (the number of moles and hence the mass) unchanged.

It comprises a number for the amount of energy required for the necessary work done (in Joules) to lift 1 kg of mass in a gas to a height at which it can become 1 degree kelvin cooler due to the decrease in density with height.
