Everything including you is matter. Matter is anything that has mass and volume.
Can be observed or measured without changing its chemical identity.
Are Properties that are observed and can not be measured with a numerical result.
can be measured and described with numerical value.
Density is how much matter (mass) is packed into a given area (volume).
You can determine density by using d=m/v
Mass is the amount of matter an object contains.
You can determine it by m=d x volume.
Amount of space a substance takes up.
Volume=lenght x width x height
A chemical property tells us how a substance behaved when it interacts with other substance.
A physical change is when something looks or feels different but doesn't become a new substance. It's like a change in its appearance or state, but it's still the same thing.
A chemical change is when substances transform into completely new ones, often due to reactions like burning or rusting.
mass of reactants=mass of products.
In any chemical reactions, the total mass of the prodcucts is the same as the total mass of reactants.
A mixture is a physical combination of two ot more substances that arent chemically joined. For examples ceral and milk.
Mixtures, puresubstance (compount and elements)
Mixture is a compound made by combining two or more different materials without having a chemical reaction. For example- cereal and milk
A pure substance is something that is made up of only one type of material. For example, pure water is only made of water molecules, and pure gold is just gold without anything else mixed in.
Elements- Can be found in the periodic table. Ex- Iron
Compounds- Composed of two or more seperate elements. Ex- water, table salt and baking soda.
Matter can be classified intontwo categories which is pure substance and mixtures.
Then pure substance can be broken into 2 categories which is elements and compounts.
Mixtures can be broken down into 2 as well which is homogenerous mixture and hetergenous mixture
