Matter Study GuideSlide2
Matter – is anything that has mass and takes up space
Element – a substance that is made up of one type of atom
Evaporation – is a change of state from a liquid to a gasSolid – has a definite volume and shape
Define the following the words:Slide3
Physical Property – can be measured without changing the identity of a
substance
Liquid – has a definite volume but not a definite shapeLaw of Conservation of Mass – mass can not be created or destroyed; applies to both a physical and chemical change
Define the following the words:Slide4
Physical Change – a change that affects one or more physical properties of a substance
Chemical Change – is when one or more substances changes into entirely new substances with different properties
Define the following the words:Slide5
Reactivity
Flammability
Two examples of chemical properties: Slide6
Stretching a rubber band
Dissolving sugar into water
Cutting your hairThese are physical changes because they do not change into some other substance, they are changing the appearance
Three examples of physical changes that matter can undergo and explain why they are physical changes.Slide7
Sugar/Yeast/Warm Water can form a gas
Milk that has soured
Burning candleThese things are chemical changes because a new substance is formed when they undergo these changes.
Three examples of
chemical changes that
matter can undergo and explain why they are physical changes.Slide8
Solid – particles vibrate
Liquid – particles slide past one another
Gas – they will spread out and moveAll particles that make up all matter are constantly in motion.
How do particles move in matter? (solid, liquids, and gas)Slide9
Each water molecule is identical because it is made up of one oxygen atom and two hydrogen atoms.
Why is water a pure substance?Slide10
Mass is the amount of matter in an object while weight is a measure of the gravitational force on an object.
How is mass different from weight?Slide11
A chemical change will change into a new substance, while a physical change does not change into a new substance.
Describe the difference between a chemical change and a physical change?Slide12
The ice will undergo a physical change because the ice will melt and turn into liquid water, but I could freeze the water and have it turn.
When ice melts is it a physical or chemical change and why?Slide13
When matter changes states the motion of the molecules and the amount of space between them changes.
What causes matter to change state?Slide14

Find the density of each substance. What substance has the lowest density?
The Popsicle has the lowest density.Slide15
Circle the box with 6 atoms.
It has a greater/higher density because there are more particles that are closer together in the area than the other image.
Look at the images below. Circle the image below that has the higher density?
Explain why that image has greater density.
