kinetic molecular theory

What is kinetic energy?

• Energy stored in objects at rest

• Energy possessed by an object due to its motion

• Energy released during a chemical reaction

• Energy absorbed during a phase change

Which of the following is NOT a state of matter discussed?

• Gas

• Solid

• Liquid

• Plasma

What does the kinetic molecular theory of gases describe?

• The behavior of gases under pressure

• The process of gas turning into a liquid

• The amount of energy needed to change a gas into a solid

• The rules for how gases behave

What happens to kinetic energy as the speed of an object increases?

• It is converted into potential energy

• It increases

• It remains constant

• It decreases

In which state of matter are particles packed together tightly with very little kinetic energy?

• Liquid

• Gas

• Solid

• Plasma

What is an ideal gas?

• A gas that perfectly follows the kinetic molecular theory

• A gas that exists only in a vacuum

• A gas that can change into a liquid at room temperature

• A theoretical gas that has no volume

What type of collision do gas particles have with each other and the walls of their container?

• Inelastic collisions

• None of the above

• Elastic collisions

• Perfectly inelastic collisions

According to the kinetic molecular theory, what do gas particles do?

• Neither attract nor repel each other

• Form bonds with each other

• Repel each other

• Attract each other

What does the average kinetic energy of gas particles depend on?

• The mass of the gas particles

• The volume of the gas

• The pressure of the gas

• The temperature of the gas

What is NOT true about gas particles according to the kinetic molecular theory?

• They are in constant random motion

• They have forces of attraction or repulsion between them

• Collisions between them are elastic

• They are far apart relative to their size
