PROPERTIES OF MATTER STATION 1

Where did the

water droplets

on the outside

of this cup

come from?

What phase

change is this?


Make a copy of this graph on your paper.

Label the phases of matter on the graph.

Write “solid” where the substance would occur as a solid.

Write “liquid” where the substance would occur as a liquid.

Write “gas” where the substance would occur as a gas.


Copy the graph on your paper.

Circle the part of the graph when a liquid is turning to a gas.

What happens to the temperature (heat energy) when a liquid

turns to a gas?

A. Does the heat energy increase?

B. Does the heat energy decrease?

C. Does the heat energy stay the same?


What happens to the kinetic energy of the water as time

increases on the graph?

A. Does the kinetic energy increase?

B. Does the kinetic energy decrease?

C. Does the kinetic energy stay the same?


The six phase changes are listed below.

List the three phase changes that absorb or require energy.

(Goes from low kinetic energy to higher kinetic energy).

Melting Vaporization Sublimation

Freezing Condensation Deposition


The six phase changes are listed below.

List the three phase changes that release energy.

(Goes from high kinetic energy to lower kinetic energy).

Melting Vaporization Sublimation

Freezing Condensation Deposition


The definition of matter says that matter needs to have two

things. What are these things?

Matter is anything that has ____________ and _____________.


Salt, woodchips, and magnetic BB’s have been mixed together.

The mixture has a mass of 100 grams.

List the steps that you would take to completely separate the

items.

Give evidence from the Law of Conservation of Mass (Matter)

to prove they are completely separated. Compare the mass of

the mixture with the ending masses of the separated

substances.


You ride your bike to your friend’s house for dinner.

Before you left you pumped up the

tires to make sure they had enough

air.

While you were at your friend’s house

the temperature dropped and it started

to snow.

When you decided to ride your bike home

you saw that the tires were flat.

You brought the bike into the garage and

saw there were no holes in the tires.

*Use your knowledge of the Kinetic Theory of Matter to

explain why the bike tires went flat.

Include the words:

-kinetic energy -temperature

-speed of molecules -volume


Karla filled her ice cube tray with 20 grams of coffee.

According to the Law of Conservation of Mass, what will

happen to the mass of the coffee when it freezes and becomes

solid iced coffee cubes?


The candle had a

starting mass of 50

grams.

The candle burned

for 2 hours and was

then put out.

The mass was then

30 grams.

Where did the other

20 grams go?


Below is a mixed list of physical and chemical

changes.

On your paper make a T chart.

Sort the changes to make one list of physical

changes and one list of chemical changes.

List of physical and chemical changes. toasting marshmallows rusting a nail cutting wood

lighting a match rotting an egg boiling water

breaking glass burning paper melting chocolate

dissolving sugar in water mixing baking soda and vinegar

Physical Changes Chemical Changes


On your paper copy the Venn diagram.

Complete the Venn Diagram using the list of signs of physical

and chemical changes.

There should be two sentences in each circle.

Signs of either a physical or chemical change.

The substance melted.

The substance was separated into two parts.

The mass decreased.

A new substance has formed.

A change in pH occurs.

A phase change occurs.

15 a.

Order the phases of matter from most kinetic energy to least

kinetic energy.

15 b.

Order the phases of matter from the molecules being the

farthest apart to the molecules being the closest together.

15.c

Draw the molecules in each phase of matter and label

the phases of matter.
