Understanding Kinetic Molecular Theory

What does the Kinetic Molecular Theory help us understand?

• The behavior of gases under different conditions

• The laws of gravity

• The process of photosynthesis

• The structure of DNA molecules

What is kinetic energy?

• Energy stored in chemical bonds

• Energy of movement

• Energy stored in an object's position

• Energy produced by heat

How do particles in a solid move?

• They do not move at all

• They move very quickly and randomly

• They vibrate in place

• They flow past one another

What kind of structure do solids have?

• Random structure

• Crystalline structure

• Liquid structure

• Indefinite structure

What happens to the shape of liquids when placed in a new container?

• It becomes a solid

• It takes the shape of the container

• It evaporates immediately

• It remains the same

Do liquids have a definite volume?

• No, never

• Yes, always

• Only when heated

• Only when frozen

How do gas particles move?

• In a straight line

• Slowly and steadily

• They do not move

• Randomly and very quickly

What is NOT an assumption made about ideal gases?

• Gas particles are attracted to one another

• Gas particles take up no space

• Gas particles collide perfectly elastically

• Gas particles are hard, round spheres

What is the shape of a gas in a container?

• Solid shape

• Crystalline shape

• Indefinite shape

• Definite shape

Can gases be compressed?

• Only at high temperatures

• No, they cannot be compressed

• Only at low temperatures

• Yes, into a smaller volume
