Question

Ideal Gas Question:
Which conditions of P, T, and n correspond to the best ideal gas? Why?
a. high P, high T, high n
b. low P low T low n
c. low P high T low n

Please explain, I don't understand! Thank you!

Answer 1

The answer is C
Gases behave most ideally under conditions of higher temperature and lower pressure.

Gases deviate from ideal behavior because the ideal gas law assumes that the molecules of the gas have no volume of their own, and that there are no interactions between the gas molecules.

Under low pressure conditions, the volume of space actually occupied by the molecules is minimized because there are fewer gas molecules present. At higher temperatures, interactions between the gas molecules are minimized because the energy of the molecules is higher than the forces of interactions between the molecules.
