science exam #1

8th grade matter

What is Matter anything that has mass or volume
what is mass the amount of stuff that is in something
what do you measure mass with? triple beam ballance
does it remain the same any where in the universe? YES
what is volume the amount of space an object takes up.
what type of units is volume measured in? international space units
can you use water displacement to find volume YES.
what is the formula to find volume L*W*H=VOLUME
what isn't matter gravity, friction, inertia, sound, velocity,light, heat.
what are the physical properties of matter ~characteristics that can only be observed with out changing the identity of matter ~density, mass per unit ~five states of matter ~change in state ~particle diagrams ~temperature scales
what are the characteristics that can only be observed with out changing the identity of matter a)mass b)volume c)density d)size e)shape f)boiling point g)melting point h)elasticity i)color j)taste/odor k)texture l)fluidity m)magnetic attraction n)state of matter
what is density mass/unit
what is the formula for density mass divided by volume
what type of thing floats in water? if density is less than density of water
what type of thing sinks in water? if the density of the object is more than the density of water
in words what is the formula for density the amount of matter divided by the amount of space something takes up
what are the five states of matter Bose-Einstein Condensate liquid solid gas plasma
is all matter made up of particles? YES
what type of particles is all matter made of? particles that are attracted to each other particles that move around as temperature increases the particles move more
what 4 things are the particles in a solid packed together tightly arranged in fixed rows held together by strong forces vibrating around a fixed position
do particles in solids have High density, fixed shape, fixed volume YES
what 3 things are the particles in a liquid a) arranged randomly b) held together by weaker forces c) flow to take up empty space
do the particles in liquids have Fixed volume, flows to fill container from the bottom up YES
do the particles in liquids have more viscous liquids are held together by stronger forces YES
what 4 things are the particles in gasses? a) arranged randomly and far apart b) barely held together c) moving fast in different directions (straight) d) crashing into each other and container (pressure)
do the particles in gasses have a fixed shape or volume NO
do the particles in gasses flow to fill container no matter what size YES

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
