Compare the densities from least dense to most dense:
water: 1.0 mercury: 13.55 corn syrup: 1.37
vegetable oil: .93
veg. oil, water, corn syrup, mercury
200
The amount of matter compared to the volume.
What is density?
200
Two or more substances that are combined without changing any of them.
What is a mixture?
200
has no definite shape and DOES have a definite volume
What is a liquid?
200
Name things that are non-matter.
light, sound, ideas, heat
200
What happens to he amount of matter when it changes states?
nothing; the amount of matter stays the same
300
Everything that takes up space.
What is matter?
300
A measure of how much material will dissolve in another kind of matter.
What is solubility?
300
How are particles in a solid arranged?
Tight, evenly spaced patterns. Particles vibrate.
300
How does heat affect solubility?
As the temperature increases, the solubility of most substances will increase.
300
Name some physical properties that can be used to describe matter.
color, shape, density, mass, volume, texture, state of matter, solubility
400
Matter that has no definite shape and takes up no definite amount of space.
What is a gas.
400
Matter that is not spread out evenly in a mixture. Some matter settles to the bottom.
What is suspension?
400
What kind of energy can make particles move faster, causing them to separate?
heat
400
Name mixtures that are suspensions.
dirt & water, orange juice and pulp, sand & water, oil & water
(A mixture where the ingredients are not spread out evenly; some of the ingredients settle to the bottom; some of them rise to the top)
400
How might a solid change it's shape?
If the solid's melting point is reached, it will change to a liquid. When it is cooled, it will turn back to a solid in a different shape.
500
The amount of space that matter takes up.
What is volume?
500
Different kinds of matter mixed completely.
What is a solution?
500
Name things that have a great solubility in water.
sugar, salt, baking soda
500
Which of the following affects the boiling point of water:
A) altitude
B) density
C) volume
D) weight
A) Altitude; water boils at a lower temperature the higher you go above sea level
