Study Notes

What are Physical Properties of Matter?

Physical properties are characteristics of matter that can be observed or measured directly.
Matter is anything that takes up space and has mass
All 5 senses can help identify physical properties: taste, smell, hear, see, touch/feel (texture)
Density describes how tightly packed particles are within an object. Objects with more density sink, objects with less density will float.
Mass is the amount of matter in an object. Measured with a pan balance and the unit is grams and kilograms
Volume is how much space an object takes up. Regular shaped objects (brick, cube, box) use a ruler or tape measure. Irregular shaped objects (orange, egg) use water displacement to measure.
Magnetism is a physical property of matter. Only some kinds of matter have this property.

States of Water

Water exists in 3 states: solid, liquid and gas
Solid state of water is ice
Liquid state is water
Gas state is water vapor
Heat is energy, when energy is added particles speed up, when energy is removed particles slow down
Evaporation is the process of a liquid turning into a gas. For example, a puddle on the sidewalk evaporates when heat is added (sun or hotter temperature) and the particles in the puddle speed up and break apart to become a gas.
Condensation is the process of a gas turning into a liquid. For example, a non insulated water bottle filled with ice water starts to drip with water droplets after a short amount of time when left at room temperature. The ice cold water in the bottle removes energy from the gas (air) surrounding the bottle and as the particles slow down they stick together and become water droplets.

Magnets

Magnets are in everyday electronics such as computers, televisions, speakers, microwaves, and maglev trains
Iron is magnetic, but not all metals are magnetic.
Magnets have 2 poles, North and South.
Unlike poles attract = pull together (NS) "opposites attract"
Like poles repel = push apart (NN, SS)
Electromagnets can be made with a battery, wire, and an iron nail. When the battery wears out it no longer works as a magnet.
A compass has a needle with a magnetic tip that points North. Earth is a giant bar magnet and has a magnetic field, which is why a compass works.

Inquiry "Law of Conservation of Matter/Mass"

You can't make or destroy matter but you can change the form (state). Solid to liquid, liquid to gas.
The new form will have the same amount of mass as the old form.

Magnetic Field

The magnetic field is the space around a magnet in which the force of the magnet acts.
The magnetic pole is the part of the magnet at which its force is strongest.
An electromagnet is temporary and caused by an electric current.
A motor is a device that uses electricity to make things move.
