Inquiry: How are solids, liquids, and gases different?

Solid Liquid Gas

Clay, Rock, Ice tray, Plastic, Sponge/foam, magnifying glass, flour, foil

Water, oil, corn syrup??, air freshener??, Hand sanitizer

Air in balloonAir freshener (evaporated)

Usually firm surfaceHas a “shape”Things usually do not pass through

Flows easier than solid, things can usually go through itUsually spreadsHas no set shape

Usually harder to see, Spreads out

State of Matter: the physical form that matter is in

based on the position and movement/energy of the atoms and molecules in that substance.

4 states: *solids, *liquids, *gases, plasma

Solids

Atoms movement and energy: atoms/molecules in a solid do not move a lot. (vibrate). Low energy

Next >

Shape-shifting ability: solids keep the same shape no matter what container they are in.

Volume: solids take up the same amount of space no matter whatcontainer they are in.

Inquiry: How are solids, liquids, and gases different?

Liquids (intermediate stage between solids and gases)

Atoms movement and energy: Atoms/molecules in a liquid move around more freely than in a solid. (Medium energy)

Next >

Shape-shifting ability: change shape based on the container it is in

Volume description: Liquids take up the same amount of space no matter what container they are in.

Inquiry: How are solids, liquids, and gases different?

Gases

Shape-shifting ability: change shape based on the container it is in

Volume description: Gas can be compressed to change the amount of space they take up. (no set volume)

Atoms movement and energy: Atoms/molecules in a gas move around quickly. (High energy)

What is Temperature???

Temperature??

Next >

Inquiry: What is the difference between solids, liquids and gases?

All matter possesses a certain amount of energy because atoms/molecules are always moving.

Solid Liquid GasTemperature measures the amount of motion/energy, and heat in an object.

(measured in Celsius (oC), Fahrenheit (oF), or Kelvin

Inquiry: What is the difference between solids, liquids and gases?

Matter: anything that takes up space. (made up of atoms/molecules)

Solid Liquid GasStates of Matter: different phase of matter based on the amount of energy the atoms have.

Inquiry: What are the different phase changes of matter?

Melting: solid to liquid.Melting point: the temperature at which a solid

turns into a liquid. (waters melting point = above OoC or 32oF)

Solid Liquid

Increasing temperature, atoms movement and energy.

Temperature measures the amount of motion/energy, and heat in an object. (measured in Celsius (oC), Fahrenheit (oF), or Kelvin

Freezing: liquid to solidFreezing point: the temperature at which a liquid

turns into a solid. (waters freezing point = 0oC or 32oF)

Liquid Solid

Decreasing temperature, atoms movement and energy.

Inquiry: What are the different phase changes of matter?

*Evaporation: liquid to gas*Boiling point: the temperature at which a liquid

turns into a gas. (waters boiling point = 100oC or 212oF)

Liquid Gas

Increasing temperature, atoms movement and energy.

Inquiry: What are the different phase changes of matter?

*Condensation (con-den-say-shun): gas to liquid

Gas Liquid

Decreasing temperature, atoms movement and energy.

Inquiry: What are the different phase changes of matter?

Sublimation(sub-li-ma-shun): solid to gas (skips over liquid stage)

Solid Gas

Increasing temperature, atoms movement and energy.

Task:

1) Match the different characteristics with the appropriate state of matter. Record it in your

notesAssessment Question:The 3 pictures below represent the atoms in

each of the 3 different states of matter. Label the picture that you think represents a

solid.

Inquiry: How do phase changes influence the water cycle?

Inquiry: What happens to the temperature of a substance during a phase change?

Phase Change: a physical change, when a substance changes its state of matter.

Ex. At boiling point, a phase change occurs from liquid to gas.

The temperature at which water becomes a gas (steam) is 100° C or 212oF. Boiling points of other

liquids may be much higher or lower than this.Next >

Inquiry: What happens to the temperature of a substance during a phase change?The melting point of a substance is one of its

most important properties.

This is the temperature at which a substance turns from a solid into a liquid.

The melting point of ice is above 0° C or 32oF. This means that water is a liquid at room temperature (20° C). Next

Do Now 1) Define Phase Change 2) For each phase change, state what state of

matter it starts off as and what state of matter it ends up as.

Which graph best represents the relative distance between the particles of most substances in their solid,

liquid and gas states?

Solids = atoms are close and low energyLiquids = atoms are further apart, moving at “medium” energyGases = atoms are spread out, and moving rapidly, “high” energy

2) Develop a model to show the relationship between heat energy and the motion and position of particles in a sample of matter. Use a group of 20 students in

an empty room to represent the particles in the following samples of matter.

a) Students represent a “solid”:

b) Students represent a “heated solid”:

c) Students represent a “liquid”:

d) Students represent a “gas”:

Students should go stay close together and shake alittle.

Students should move apart alittle and shake

more.Students should

separate and walk a around the

classStudents should spread out and run around the room

3) Compared to the particles in a hardened lava sample, the particles in a liquid lava sample

a) Lower temperature b) Less kinetic energy

c) Are moving faster d) Are closer together

Yes; not a shape shifter

No; isa shape shifter

No; isa shape shifter

Yes; takes upthe same am’tof space

Yes; takes upthe same am’tof space

No; spreads out to fit the space it’s in
