Question

Which statement describes a limitation of the kinetic-molecular theory for a gas? The theory assumes that particles do not experience intermolecular forces. The theory states that pressure is inversely proportional to volume. The theory assumes that particles are in random and continuous motion. The theory states that pressure increases with temperature.

Answer 1

Answer:

The theory assumes that particles do not experience inter-molecular forces.

Step-by-step explanation:

The kinetic molecular theory for gas states that the gas particles move freely and they are in constant motion and exhibit elastic collisions.

Out of the given statements, the one that is the limitation of the kinetic-molecular theory for a gas is - The theory assumes that particles do not experience inter-molecular forces.

The theory states that pressure is inversely proportional to volume- This is true as since the pressure decreases the volume must increase.

The theory assumes that particles are in random and continuous motion- yes this is true as per definition.

The theory states that pressure increases with temperature. yes this is also true as the more the temperature, the more the pressure.

Answer 2

I think the correct answer from the choices listed above is option A. A  limitation of the kinetic-molecular theory for a gas is the theory assumes that particles do not experience intermolecular forces.This cannot be completely true since interactions between particles is normal.
