5th grade matter rev

condensation If you cool a gas, it may turn into a liquid. Examples: clouds, dew, water droplets on the outside of a glass on a hot day.
When you heat matter, the atoms and molecules move faster nd usually spread apart
In a solid, the molecules are... tightly packed and barely moving.
In a gas, the molecules are... moving fast and spread apart.
solution a mixture in which one substance dissolves into another.
solid, liquid, gas Three states of matter
melting If you heat a solid, it will turn into a liquid.
evaporation If you heat a liquid, it will turn into a gas.
freezing If you cool a liquid, it will turn into a solid.
elements There are over 100 pure substances.
atom the smallest part of an element
compound 2 or more elements combine to make a completely new substance (water is a compound)
molecule the smallest part of a compound. Two or more atoms join together chemically.
water H20 is a compound known as ____.
salt NaCl (sodium chloride) is a compound.
mixtures substances that combine but can be separated again.
physical change Things we can change about matter but still have the same matter we started with. (i.e. crumbling a sheet of paper)
chemical change Things we can change about matter to get something new. (i.e. burning a sheet of paper, we are changing the type and arrangement of atoms in the molecules to get ashes)
physical properties a property that can be observed without changing what a substance is made of (i.e. color, smell, taste, texture)
mass the amount of matter in an object
volume the amount of space an object takes up (Volume=mass x width x height)
density the amount or capacity of a unit's volume or area.
solid has a definite shape and the molecules are tightly packed together.
liquid Molecules not as tightly packed together. The shape will be determined by the container's shape. It has a definite volume.
gas no definite shape or volume. Take the shape of its container and the molecules are spread far apart. Molecules are always moving around
effects of temperature molecules move around more when the temperature increases. Molecules bounce and spread as solids melt. Liquids will evaporate when the temperature is increased enough to change the molecules into a gas.
