For a gas, the compressibility factor Z depends ona)pressure and volum...
Explanation:
The compressibility factor Z is defined as the ratio of the actual volume of a gas to the volume predicted by the ideal gas law. It is a dimensionless quantity that is used to correct for the deviations from ideal gas behavior. The value of Z depends on the pressure, volume, and temperature of the gas.
Pressure and Temperature:
The compressibility factor Z is strongly dependent on the pressure and temperature of the gas. At low pressures and high temperatures, the gas behaves more ideally and the value of Z approaches 1. At high pressures and low temperatures, the gas deviates more from ideal behavior and the value of Z decreases.
Volume and Temperature:
The compressibility factor Z is also dependent on the volume and temperature of the gas. As the volume of a gas is reduced, the gas molecules are forced closer together, and intermolecular forces become more significant. This can cause the gas to deviate from ideal behavior and the value of Z to decrease. Similarly, at low temperatures, the gas molecules have less kinetic energy and are more likely to interact with each other, causing deviations from ideal behavior and a decrease in the value of Z.
Pressure, Volume, and Temperature:
While the value of Z is dependent on all three variables, pressure and temperature are typically the most significant factors in determining the compressibility factor of a gas. Therefore, the correct answer to the question is option B, as the compressibility factor Z depends primarily on the pressure and temperature of the gas.
