MatterA. Every object that takes up space is made of
matter.
![Page 3: Matter and Magnets Matter A.Every object that takes up space is made of matter.](https://reader035.fdocuments.us/reader035/viewer/2022070406/56649e055503460f94af1f43/html5/thumbnails/3.jpg)
States of matterA. Matter can exists in different states: solid,
liquid, and gas.
Solid Liquid
Gas
Water exists as a solid, liquid and gas.

Phase changesA. To change between the different states of matter,
solid, liquid, and gas, water goes through phase changes.
Solid
Liquid
Gas
Phase changes can be caused by changes in temperature.

BoilingA. When water reaches
the boiling point, it changes from a liquid to a gas, commonly called steam.

EvaporationA. When water evaporates, it changes from liquid
water to a gas without boiling.
On a sunny day, water will quickly evaporate from this towel on the clothesline, and from the soil of the potted plant .

Evaporation as part of a cycleA. When water evaporates, it changes into a gas.
Evaporation is part of the water cycle. Water in the ocean evaporates and then forms clouds.

Freezing When the
temperature reaches the freezing point,water changes from a liquid state to a solid, commonly called ice.

MeltingWhen ice melts, it changes from a solid to a liquid.

Physical properties remain the same
A. Physical properties remain the same as the material is reduced in size.
B. As an ice cube melts, it remains the same substance. A piece of paper that is torn in half is still paper.

MassA. Mass is the amount
of matter an object holds.
B. Air has mass.

VolumeA. As a balloon is
blown up, the volume of air increases.
