Properties of matter
It is a characteristic of an object
Property
It is an instrument to compare a mass that you know with one that you don’t know.
Pan balance.
Three phases of matter are:
Solid, liquid and gas
It is a combination of two or more substances
Mixture
It is a change in the size, shape or state.
Physical change
It is the amount of matter that makes an object.
Mass
Metric units to measure mass are:
Miligram, gram and kilogram
Matter that doesn’t have a definite shape but takes up a definite amount of space.
Liquid
In this process, a magnet can be used to separate substances that are attracted to a magnet.
Magnetism
Examples of physical changes
Break a pencil, tear a paper or evaporate water.
It is the measure of the force or pull of gravity between and object and Earth.
Weight
It is the amount of space that matters takes up.
Volume
It is matter that has a definite shape and usually takes up a definite amount of space.
Solids
This process uses a filter to separate substances.
Filtration
It is a change that produces a completely different substance.
Chemical change
It is a force that acts on moving electric charges and magnetic materials.
Magnetism
Metric 7nits to measure volume or capacity.
Liters and milliliter.
It is a substance 5hat exists naturally in the three phases:
Water
It is the change from a liquid into a gas.
Evaporation.
Example of chemical change that happens quickly.
Burning wood.
It is the property that compares an object’s mass with its volume.
Density.
It is the law that states that the parts of an object will have the same total mass as the whole object.
Law of conservation of mass.
The form in which particles are arranged and move.
Phase of matter.
Main property of mixtures
They are not chemically combined.
Example of chemical change that happens fast.
Rusting iron.
