Slide1

Water: States of Matter

By: Cammie GoodmanSlide2

Icicles

, raindrops, an invisible gas in the air—these are all forms of water.

Water can be a

solid, a liquid, or a gas

.Water can also change from one of these forms to anotherSlide3

States of Matter

Matter

is anything that takes up

space

and has

weight

Exist in different physical forms, called

states. (solids, liquids,

gases)Slide4

A solid is matter that

keeps its own shape

. Slide5

A liquid is matter that

takes the shape of its

container. Slide6

A gas is matter that

spreads out

in all directions

.Slide7

Water

is a kind of matter that is found in nature in all three states

.

Earth’s water is found in the liquid state in

oceans, lakes, and rivers.

Frozen water or ice is in the

solid state

.

Frozen water is found in the

polar ice caps

and in large ice sheets called

glaciers

. Slide8

Water in its gas state is called

water vapor.

Water vapor is one of the

gasses

in the air. Slide9

Earth’s water changes

state: glaciers melt, dripping water forms icicles, puddles dry up and water vapor becomes drops of dew. Slide10

Melting

Melting is the change of matter from a

solid to a liquid

.

When enough

heat energy

is added to the solid ice cubes, they

melt

.

Heat makes the

particles

of frozen water

move faster and farther apart

. The solid becomes liquid water.

When

heat energy

is added to matter, it gets

hotter

. Its temperature

rises

.

Temperature

is a measure of how much

heat energy

and object has. Slide11

Evaporation

Evaporation is the change of matter from a

liquid to a gas

.

When a liquid changes to a gas, we say it

evaporates.

If you

heat

a pot of water on a stove, the water particles start to

move faster

, as they move

farther apart

.

When

the temperature of the water reaches

100

˚

C

, the water

boils

, or forms

bubbles of gas

. Slide12

Evaporation

Water does have to

boil to evaporate

. Evaporation can happen at

different temperatures, when water particles get enough heat energy. Then those particles leave the liquid water and go in the air as a gas—water vapor. Evaporation happens faster

when temperatures are

high

. When liquid water begins to boil at 100

˚

C, it evaporates

quickly.

Slide13

You

may see a cloud of “steam” rising from a pot of boiling water. What you see is not water vapor. Water vapor is a

clear, colorless gas

. The cloud is a

mist, made up of tiny droplets of liquid water that condense from water vapor. Slide14

Condensation

Condensation

is the change of matter from a

gas to a liquid

.

When a gas changes to a liquid, we say it

condenses

.

If it is a hot sunny day and you have a cold glass of water filled with ice cubes. You notice that drops of water

form on the outsid

e of the glass. The drops form as

water vapor in the air

condenses on the cold glass. Slide15

When water vapor

loses heat, its particles move more slowly. They move

closer

together. The water vapor changes

to liquid water. When liquid water gets cold enough, it freezes. Freezing is the change of matter from a liquid to a solid.

As liquid water

loses heat energy

, its particles move more

slowly.

If the water loses enough heat, it becomes a

solid—ice

.

Water freezes at

0

˚

Discussion Question:

When the air cools at night, the drops of water called dew form on the grass. How do the drops form? Why do they disappear during the

day?Slide17

2. Which

statement BEST describes what happens to water when it changes state from a liquid to a solid?

Its particles begin to move faster

Its particles do not move at all

Its particles evaporateIts particles move more slowly. Slide19

3. What

happens to water when it evaporates?

It becomes a solid

It becomes droplets

It is no longer matterIt becomes a gas. Slide20

4. What

happens to liquid water at 0˚C?

It becomes a solid

It becomes air

It does not changeIt becomes a gas.
