Kinetic Molecular Theory

What is a fundamental assumption about gas particles according to the Kinetic Molecular Theory?

• They are stationary.

• They are always in motion.

• They only move when heated.

• They attract each other strongly.

According to the Kinetic Molecular Theory, what can be assumed about the space occupied by gas particles?

• They occupy a significant portion of the total volume.

• They are tightly packed together.

• They are essentially dimensionless points, and the gas is mostly empty space.

• They are always in contact with each other.

How does the Kinetic Molecular Theory explain the phenomenon of pressure in a gas?

• Pressure is caused by the gravitational pull between gas particles.

• Pressure results from gas particles transferring kinetic energy to the container walls during collisions.

• Pressure is due to the strong attractive forces between gas particles.

• Pressure is created by gas particles remaining static within the container.

What is the relationship between the average kinetic energy of gas particles and the temperature of the gas, as described by the Kinetic Molecular Theory?

• They are inversely proportional.

• They are directly proportional.

• They are unrelated.

• Kinetic energy decreases as temperature increases.
