The three commons states of matter.
solids, liquids, and gases
All matter is made out of these incredibly tiny particles.
atoms
This property measures HOW MUCH matter is in an object.
mass
The property measures how much SPACE an object takes up.
volume
This property of matter measures how "tightly packed" an objects matter is.
Density
For anything to be matter, it must do these two things.
have mass and take up space
My particles hold together and hardly move. I have a definite shape and volume. I am the ___________ state of matter.
solid
We measure mass using this metric unit.
grams
We measure volume using these metric units (name at least one).
milliliters (mL) and cubic centimeters (cm^3)
The math formula for finding density (hint: it uses two other properties of matter).
mass divided by volume (mass / volume = density)
The temperature where a solid turns into a liquid because of heat.
melting point
My particles spread apart very easily and quickly. I don't have a definite shape, and my volume can change as well. I am the _________ state of matter.
gas (gaseous)
You use this tool to measure an object's mass.
a balance(also accepting 'scale,' but technically that measures weight - science is weirdly specific, but it'll make sense if you spend enough time with it)
You use this tool to measure the volume of a liquid.
graduated cylinder (A beaker also works!)
Liquid A has a density of 2 g/mL. Liquid B has a density of 4 g/mL. Which one will sink to the bottom?
Liquid B (More dense matter sinks below less dense matter; lighter matter rises above denser matter)
The temperature where a liquid turns into a gas because of heat.
boiling point
My atoms stay together, but can also move around. I don't have my own shape, but I have volume. I can be poured. I am the ___________ state of matter.
liquid
True or False: When you pour a can of coke into a glass, the volume changes.
False - The coke still takes up the same space, so its volume is still the same. The SHAPE of the liquid changed.
A candy bar has a density of .95 g/mL. Water has a density of 1.0 g/mL. Will the candy bar sink or float?
Float- The candy bar has a lighter desnity than the water, so it rises above the more dense water.
This state of matter can be found on the sun, in lightning, and in flourescent light tubes.
Plasma
If I add heat to particles, how will those particles begin to change?
The particles will move quicker and will begin to spread apart. If you add heat, the particles do more 'work.' "Heat is work and work is heat."
If you cut an apple into slices, has the mass of the apple changed?
The mass has not changed. Even though it has been cut into pieces, if you put them back together, the mass would be the same as when you started!
A box has a length of 6 cm, a width of 5 cm, and a height of 3 cm. What is the box's volume?
90 cm^3
Mr. Rogers has a pear with a mass of 60 grams and a volume of 40 mL. Will the pear sink or float? (Remember the math formula for density!)
Sink- The pear's density will be 1.5 g/mL, which is more dense than the 1.0 g/mL of water.
