Answer 1

High pressure and Low temperatures

Step-by-step explanation:

correct answer on edge.

Answer 2

The two conditions that can limit the usefulness of the kinetic-molecular theory in describing gas behavior are "high pressure" and "low temperatures". At low temperatures or high pressures, real gases deviate significantly from ideal gas behavior. Because of this, the two assumptions of the kinetic-molecular theory (where gas particles occupy a negligible fraction of the total volume of gas and the force of attraction between gas molecules is zero) would become questionable.
