States of Matter
True or False: Matter can be a solid, liquid, or gas.
True
the amount of space an object takes up
volume
a change in a substance without changing the makeup of the substance
Physical changes
consists of two or more substances that are combined together.
mixture
Units for measure for mass can include
g - gram
kg - kilogram
All matter is made up of ___________________.
Atoms
the amount of material in a substance
mass
a change in matter that creates a new substance. This can also occur when the atoms in an element or compound combine to form a new substance.
chemical changes
these are mixtures where all the substances are spread evenly throughout.
solutions
Three different states
_________________ - particles that are closely packed together. Solids have a definite shape & definite volume
_________________ - particles that are not as close together but flow together. Liquids have no definite shape but have a definite volume.
_________________ - particles are incredibly far apart. Gasses have no definite shape & no definite volume.
Solid, liquid, gas
If matter is only made up of one atom this is called an ___________________.
element
the amount of force gravity exerts on matter
weight
cannot be easily reversed
With solutions you have two different pieces:
A ____________________ - the substance that dissolves the other substances
A ____________________ - the substance that is dissolved
solvent, solute
Real world examples of solvent and solute
sweet tea (solvent) sugar (solute)
If you combine multiple atoms of different elements this is when a _____________ forms.
compound
We can use ________________________ to help us find the volume of irregular shapes
water displacement
Examples of a physical change occurring can be:
___________________________
___________________________
___________________________
Shape change
Size change
State change
the amount of solute that is dissolved in the solvent
concentration
A gas can go to a liquid through ___________________.
A liquid can go to a solid through ___________________.
condensation, freezing
A solid can go to a liquid through _________________.
A liquid can go to a gas through __________________.
melting, evaporation
the amount of matter in a certain volume
Density
Examples of a chemical change occurring can be:
________________________________
________________________________
________________________________
________________________________
________________________________
________________________________
Change in color
Presence of light or sound
A change in temperature or the presence of heat
Odor change
Production of a gas
The formation of a precipitate
when there is less than a normal amount of a solute in the solvent
diluted
How is weight different from mass?
Mass is the amount of matter in a substance and weight is the gravitational pull
