Kinetic Model of Matters (NA Stream)

Define the Kinetic Model of Matters.

• The particles that made up of matters are in random motion

• The particles that made up of matters are always moving

• Matters is made up of many tiny particles

• All of the above

In the Brownian Motion experiment, what are the lighted dots that are seen to be moving randomly and continuously?

• Tiny Moving Light

• Tiny Moving Air Molecules

• Tiny Moving Dust Molecules

• Tiny Moving Dust Particles

Which of the following does NOT has a fixed volume?

• Solid

• Liquid

• Gas

• All of the above

How does the Kinetic Model of Matters explain why gas is compressible?

• There is lots of spaces between gas molecules and the repulsive intermolecular forces are strong

• There is little spaces between gas molecules and the repulsive intermolecular forces are strong

• There is lots of spaces between gas molecules and the repulsive intermolecular forces are weak

• There is little spaces between gas molecules and the repulsive intermolecular forces are weak

Liquids usually expand more than solids when heated through the same rise in temperature.

Which of the following best explains the situation?

• Liquid molecules move faster than the solid molecules.

• The forces between liquid molecules are weaker than the forces between solid molecules

• Liquid molecules expand more than the solid molecules.

• Liquid molecules are bigger than the solid molecules.
