Kinetic Model of Matter

Container 2 has a higher pressure than container 1. Why is this so?

• There is more collision among the particles.

• more frequent collisions with the walls of the container

• more force is exerted on a certain area

• The temperature is increased.

Which container will have a lower pressure?

• left

• right

• they both have the same pressure

• I don't know

What happens to the pressure of a gas when temperature is increased?

• decreases

• not affected

• increases then decreases

• increases

Which of the following is NOT a part of the Kinetic Theory of Matter?

• All matter is made up of tiny particles.

• Occasionally, particles stop moving.

• Particles are always moving in random paths.

• The type of movement of particles depends on the amount of energy.

The Kinetic theory of matter states that _________________ ,

• Some matter is made up of atoms

• All atoms are constantly in motion

  
  

• There are attractive forces between molecules

  
  

• The particles that make up solids do not move

  
  

What is Brownian motion?

• The movement of water molecules in a beaker

• The movement of air molecules

• The movement of solid molecules

• The movement of smoke particles in air

What evidence does Brownian motion provide about molecules of a gas or liquid?

• Molecules are close together

• Molecules are far apart

• Molecules move continously but randomly

• Molecules move continously and randomly

According to the Kinetic Molecular Theory a liquid's (SELECT ALL THAT APPLY)

• particles are held close together by intermolecular forces

• particles are in constant motion

• particles are vibrating in place and closely packed

• particles are not moving

No definite shape or volume

• solid

• liquid

• gas
