Which phrase describes the motion and attractive forces of ideal gas particles?

• random curved-line motion and no attractive forces

• random straight-line motion and strong attractive forces

• random straight-line motion and no attractive forces

• random curved-line motion and strong attractive forces

According to the kinetic molecular theory, which statement describes the particles in a sample of an ideal gas?

• The particles have attractive forces between them.

• The particles are considered to have negligible volume.

• The particles are constantly moving in circular paths.

• The particles collide, decreasing the total energy of the system.

A real gas behaves most like an ideal gas at

• average potential energy of its particles

• ionization energy of its particles

• low pressure and high temperature

• activation energy of its particles

Which of the following is NOT a part of the kinetic molecular theory?

• Gas particles are separated by large distances relative to their size

• Gas particle move in random and stright-line motion

• Gas particles have no attractive forces

• Gas particles stay close together and collide often

Which of the following is NOT a part of the kinetic molecular theory of gases?

• Gases move in random, constant, straight-line motion

• Gases are separared by great distances

• Gases are attracted to each other

• Gases transfer energy when they collide
