States of Matter

Physical Science

Multiple Select

Check the 3 assumptions of the kinetic theory:

• all matter is composed of small particles

• particles are in constant, random motion

• particles collide with each other and the walls of their container

• particles do not move

• as particles heat up, they slow down

Poll

When particles collide, do you think they keep the same amount of energy or does it change?

• yes, the amount of energy changes

• no, the amount of energy stays the same

Answer:

When particles collide, the amount energy DOES change!

Multiple Choice

What do you think happens to particles if you change the temperature of the substance?

• nothing, the particles stay the same

• the particles will move at a different rate

Solids

• because the particles are tightly packed together, people like to think they are not moving

• THIS IS NOT TRUE!!! 

• the particles in solids are moving, just not as quickly

• that's why we say the 'vibrate in place'

Multiple Choice

How do the particles in solids behave?

• they vibrate in place

• they slide past each other

• they move freely

• they move so fast they create ions

Multiple Select

Which 2 vocabulary words talk about the phase change that occurs when solids turn into liquids?

• heat of vaporization

• heat of fusion

• melting point

• freezing point

• diffusion

Liquids

• particles move faster than those in solids

• can "flow"

• definite volume

• can change shape to fit in a container (think about pouring Dr. Pepper out of a 2-liter bottle into a glass)

Multiple Choice

How do the particles in liquids behave

• they vibrate in place

• they move freely

• they slide past each other

• they move so quickly they create ions

Multiple Select

Check all that apply about liquids:

• they can "flow"

• they have a definite volume

• they have a definite shape

• they can change shape

• they can diffuse

Multiple Select

Which 2 vocabulary words talk about the phase change that occurs between liquids and gases?

• heat of fusion

• heat of vaporization

• boiling point

• freezing point

• melting point

Gases

• particles move fast and freely

• have no definite volume or shape

• particles will spread out to fill up the container they are in

Multiple Choice

How do the particles in gases behave?

• the vibrate in place

• they move freely

• they slide past each other

• they move so quickly they create ions

Poll

Who would smell the body spray first if I stood in one corner of the room and sprayed it?

• me

• someone across the room from me

• the person closest to me

Poll

Who would smell the body spray last?

• me

• someone close to me

• someone across the room from me

Answer:

Because I was the one to spray the body spray, I would smell it first. Then people near me would smell it. The last people to smell it would be those across the room from me,

Multiple Select

Why do gases not have a definite shape or volume? Select all that apply:

• the particles move freely

• gases diffuse to fill whatever container they are in

• the particles are really slow

• they cannot be contained

Plasma

• particles move so fast they create positively and negatively charge ions

• have the highest temperatures of all the states of matter

• most common state of matter because all stars are made of plasma

Multiple Choice

How do the particles in plasma behave?

• they move freely

• they vibrate in place

• they move so quickly they create ions

• they flow past each other

Heating Curve

• as you add heat (energy), particles begin to move faster

• solids (less heat, slowest particles) melt and become liquids

• liquids (medium heat, faster particles) vaporize and become gases

• gases (high heat, fast particles) can be super-heated to form plasma (highest heat, fastest particles)

Multiple Select

What happens as particles heat up? Check all that apply:

• they begin to move faster

• they spread farther apart

• they begin to move slower

• they get closer together

• they have more energy
