solubility
Forms when different particles of matter mix evenly.
Which is a liquid?
--uncooked oatmeal
--milk
--snow
--ice
milk
Compares an amount of matter to the amount of space it takes up.
density
Explain how you can make something more dense than water float.
You can make something more dense than water float by adding air to it.
Term for anything that takes up space and has mass.
matter
Matter that has definite volume and takes the shape of its container.
liquid
Which has the greatest solubility in water?
--ice
--paper
--sugar
--sand
sugar
Matter is made up of small bits called _________.
particles
Explain how you can make something less dense than water sink.
You can add something more dense than water to it until it sinks (i.e. lead weights).
Matter that has no definite shape and takes up no definite amount of space.
gas
Ability of matter to float in a liquid or gas.
buoyancy
Which is a gas?
--brick
--water vapor
--oil
--vinegar
water vapor
Submarines can float or sink by controlling their _________.
buoyancy
Using the terms volume and mass and their definitions, compare a cup of popped popcorn with a cup of cooked rice.
The volume may be the same, but a cup of cooked rice has a higher mass than popped popcorn. The popcorn is less dense.
What happens when one material forms a solution with another material.
dissolves
Matter that has a definite shape and volume.
solid
Which is most buoyant in water?
--sugar
--penny
--lead weight
--wood
Adding _____ makes particles in matter move faster.
heat
When a solid dissolves in water, the particles spread out in the water. If you heat the solution so that the water evaporates, the water goes away and the particles of the solid are left behind.
Amount of matter something contains.
mass
Amount of space that matter takes up.
volume
Which has the most mass?
--basketball
--maple leaf
--elephant
--penny
elephant
A liquid measuring cup measures the _______ of a liquid.
volume
Describe how the arrangement of particles of water is different in its liquid and solid states.
Particles in water's solid state are close together and move back and forth around one point. In water's liquid state, the particles move from place to place.
