100
saturated
A solution that is _____________________, contains all the solute that can be dissolved without changing the temperature.
100
dilute
Little solute in a solution in comparison with the amount of solvent.
200
V = L x W x H
What is the formula for calculating the volume of an object?
200
Electrons
The atoms in molecult share ____________________.
200
True. For example, iron will always have the same density, no matter how large a piece of iron it is.
True or False The density in a substance will have the same density, not matter how much of the substance is measured.
200
Solute
In a solution, the substance that dissovles is called the __________________________.
200
Atom
What is the smallest part of an element that has the properties of the element?
300
Metals
Most elements are (metal, pure).
300
Crystals
Particles of salts arrange themselves in a regular geometric pattern to form ________________.
300
Evaporate
If the temperature in a liquid is high enough, the particles in the liquid will ____________________.
300
Properties
The materials in a simple mixture can be seperated because they have different___________________.
300
Mixture
In a _________________, materials are placed together but do not form a bond.
400
If an object's density is less than the liquid's density, it will FLOAT. If the object's density is greater than the liquid's density, it will SINK.
If an object's density is less than the liquid's density, it will ( float, sink ).
400
Volume
An object that takes up more space than another object has a greater ?
A. Volume
B. Mass
C. Density
D. Weight
400
When water vapor is cooled.
When does dew form?
400
Alloy
Brass and Bronze are examples of a type of mixture called an ___________________.
400
Saturated
What is a solution that contains all the solute that can dissolved without changing the temperature?
500
You divide its mass by its volume. D = M divided by V
How do you find the density of an object?
500
Elements in each COLUMN have similar chemical properties.
How can you tell what elements in a periodic table have similar properties.
500
The particles have less space between them.
Why do most materials get smaller when they cool?
500
Whether a material floats, or is bourant, depends on the density of the material and the liquid. If the object's density is less than the density of the water it is in, it will float.
How are bouyancy and density related to each other?
500
Electron
___________________ move around protons and neutrons. They have a negative charge. They may join or leave atoms, or be shared between atoms.
