Sentences with phrase «ideal gas constant»

To calculate the molar densities from the weather balloon measurements, we converted all of the pressures and temperatures into units of Pa and K, and then determined the values at each pressure using D = n / V =P / RT, where R is the ideal gas constant (8.314 J / K / mol)

T = temperature p = pressure V = olume R = ideal gas constant Cp = ideal gas heat capacity = 5 / 2R g = gravitational constant rho = density = 1 / V z = vertical spatical coordinate.

n is the number of moles of gas in question and R is the ideal gas constant.

Not exact matches

For example any (constant) volume of ideal gas at room temperature (20 °C) increases its pressure by a factor fo 4.3 when heated to 1000 °C.

Since this commercial space is set in an ideal and well known location, alongside the San Cas Warehouse and other business establishments such as Atlantic Bank, gas stations, Bowen & Bowen Ltd, schools it provides the added benefit of constant clientele.

The gas on the bottom behaves like an ordinary ideal gas, after all, and expands when warmed at constant pressure.

c) It is completely irrelevant to the discussion at hand, involving a simple ideal gas in an ordinary vertical column with constant g.

If we assume a constant temperature in the adiabatically isolated container, one gets the following formula for the density of an ideal gas:

The gas at the top of the tube would be warmed (thus increasing its pressure slightly (ideal gas laws temperature change constant volume tube) and like a piston this pressure increase would propagate down the tube at the local speed of sound in the gas causing adiabatic heating of the gas in each subsequent layer until it reached the bottom of the tube, instantly replacing the heat lost to the silver wire.

Nor is pressure constant in a gravitationally bound column of ideal gas.

So if one uses the heat engine to do external work, the gas in the cylinder will indeed drop to zero in temperature as all of its internal energy drops to the bottom to maintain a constant temperature difference right up to where the temperature of the ideal gas at the top reaches zero.

where g is the gravitational acceleration (presumed approximately constant throughout the spherical shell) and cp is the heat capacity per kilogram of the particular «ideal» gas at constant pressure.

The constant speed moving parcel of the ideal gas is the same solution as still air for hydrostatic equilibrium.

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.

Furthermore the volume V = NkT / P should stay more or less constant since k and P are constant while NT (product of number N of molecules with temperature T) should also remain roughly constant because although N has decreased very slightly, this is offset by the corresponding slight increase in T. (This is how I would address Eli's concern that condensation violates the ideal gas law.)

We generally believe that the standard notations that introduce a gas - specific constant to the ideal gas law are misleading.

Increase the temperature of an ideal gas and the pressure and / or volume increases (assuming a constant amount of gas).

Given the ideal gas law, and the fact that the flask contains a constant volume, that means the increase in pressure for pure CO2 would in the flask would result in less than a 2.6 x10 ^ -6 oC increase in temperature.

Also, this is ideal gas «constant rapid motion» by which it means travelling at great speeds through empty space, it does not mean the vibrational movement of the molecule which is anyway confined by by the other real gas molecules under gravity around it.
