Matter and it's Physical Properties

Remember what Matter is? Anything that takes up space and has mass

Do you remember your States of Matter? Solid Liquid Gas Plasma (we don’t worry about plasma in 5 th grade)

So what are all the physical properties of matter? Remember that when we learned about traits, physical traits were those that were part of the body of the organism – not behaviors. So physical properties of matter are simply the properties that are part of the substance without changing it into a new substance (no chemical changes). These are things you can detect with your senses or measure!

Examples of physical properties

We will spend most of our time on: Density Solubility Conductivity Magnetism You should already be able to find the following using your measurement skills! Length Mass Volume

Physical Properties of Matter Boiling Point – The temperature at which liquid matter turns into a gas. The boiling point of water is 100 o C.

Physical Properties of Matter Melting Point – The temperature at which solid matter turns to liquid Freezing Point – The temperature at which liquid matter turns to solid The freezing/melting point of water is 0 o C.

Mass The amount of matter in an object The gram is the metric unit for mass Physical Properties of Matter

Volume The amount of 3-dimensional space an object occupies. Also known as Capacity. Can be measured by the amount of water an object can move or displace. All states of matter have volume, but only solids have a set shape.

Physical Properties of Matter Density – The amount of matter within a certain amount of volume. We will focus on relative density in water. Which do you think has a greater density? Bowling Ball or Soccer Ball

Physical Properties of Matter Density – The more dense an object the more it will sink and the less dense an object the more it will float in water.

Physical Properties of Matter Solubility – The ability for a substance to dissolve In a solution ingredients of a mixture are spread out evenly throughout. You usually cannot see the dissolved ingredients (other than through color change).

Physical Properties of Matter Magnetism – Property of attraction to a magnet. The entire Earth has a magnetic field!

Physical Properties of Matter Conductivity: Ability of a substance to allow electricity or heat to pass through it. Metals are good conductors of heat and electricity. Materials known as insulators block heat or electricity. Thermal (heat) insulators are things like styrofoam Electrical insulators are things like: rubber, plastic, cotton
