a plot of PV/RT against Pext gives a lower value than the ideal at moderate pressures and a higher value than the ideal at very high pressures for most gases. select all the statements that correctly account for this behavior
-at low pressures gas particles repel each other
-at very high pressures the molecular volume of the gas particles is significant
-at low temps, the gas particles are moving at slower velocities
-at moderately high pressures there are significant intermolecular attractions
-at very high pressures, the molecular volume of the gas particles is significant
-at moderately high pressures there are significant intermolecular attractions

Respuesta :

At very high pressures, the molecular volume of the gas particles is significant.At moderately high pressures there are significant intermolecular attractions is the statements that correctly account for this given behavior.

An equation of states is PV = nRT. Three variables are P, V, and T. They are variables because they indicate the pressure, volume, and temperature of a gas in a certain condition as well as other physical characteristics. The ideal gas constant (R) is a constant that may be found in chemical literature, and the number of moles (n) may be maintained constant. Moles (n) may be set to PV / RT as follows: n = PV / RT. T / V ratio becomes important because pressure (P), which is directly proportional to T and indirectly proportional to V, depends on it.Volume (V) is a function of T/P, with V being directly proportional to T and indirectly proportional to P. PV is a necessary condition for temperature (T), which is directly proportional to variations in both P and V.
