Deviations from Ideal Gas Behavior

AP Chemistry· difficulty 4/5

Real gases deviate most from ideal-gas behavior at

A
$Low pressure and high temperature$
B
$STP exactly$
C
$High pressure and low temperature$

D
$Conditions where Kelvin equals 1$

Explanation

Ideal gas assumes negligible volume + no intermolecular forces. High P (compression) + low T (slow molecules) make finite molecular volume and attractions matter — biggest deviations.
