The relationship between volume V, pressure P, and absolute temperature T of an ideal gas is PV=xT Where x is a constant. The value of x depends upon what?
p v = n r t
n is the amount of gas (number of moles)
r is the gas constant (a "fudge factor" for meshing assorted units of pressure, temperature, and volume)
In PV=xT, x depends only on the amount of gas present.
In the equation PV = xT, where V represents volume, P represents pressure, T represents absolute temperature, and x is a constant, the value of x depends on the particular gas being considered. This constant is known as the ideal gas constant or the molar gas constant, denoted by the symbol R.
The ideal gas constant, R, has a specific value and depends on the units used to express volume, pressure, and temperature. The most commonly used value for R is 0.0821 L·atm/(mol·K), which is valid when volume is expressed in liters, pressure in atmospheres, and temperature in Kelvin.
However, if different units are used, the value of R will change accordingly. For example, if pressure is measured in Pascals (Pa) instead of atmospheres and volume is measured in cubic meters (m3) rather than liters, then the value of R will be different. In this case, the value of R is approximately 8.314 J/(mol·K).
Therefore, the value of x in the equation PV = xT depends on the choice of units for volume, pressure, and temperature and can be determined by using the appropriate value of the ideal gas constant, R, for those units.
