Which of the following statements correctly describes the behavior of nitrogen gas under ideal conditions according to the Ideal Gas Law?
A
Nitrogen gas behaves as an ideal gas at high pressure and high temperature.
B
Nitrogen gas behaves as an ideal gas at high pressure and low temperature.
C
Nitrogen gas does not follow the Ideal Gas Law under any conditions.
D
Nitrogen gas behaves as an ideal gas at low pressure and high temperature.
Verified step by step guidance1
Begin by understanding the Ideal Gas Law, which is expressed as , where is pressure, is volume, is the number of moles, is the ideal gas constant, and is temperature.
Recognize that the Ideal Gas Law assumes no interactions between gas molecules and that the volume occupied by the gas molecules themselves is negligible compared to the volume of the container.
Identify the conditions under which real gases behave most like ideal gases. Real gases tend to behave ideally at low pressure because the molecules are far apart, minimizing interactions, and at high temperature because the increased kinetic energy overcomes any intermolecular forces.
Evaluate the given statements based on the conditions for ideal gas behavior. High pressure and low temperature increase interactions between molecules, making gases deviate from ideal behavior.
Conclude that the correct statement is: Nitrogen gas behaves as an ideal gas at low pressure and high temperature, as these conditions minimize molecular interactions and the effects of molecular volume.
