Matter and Energy Physical Properties of Matter

2nd common misconception about properties of matter

Another common misconception is that all metals are magnetic. However, only the metals iron, nickel, and cobalt are magnetic. Other metals such as steel are a mixture of metals that contain iron and nickel which makes them magnetic as well. While these metals are magnetic, there are metals, such as aluminum and copper, which are not magnetic at all.

3rd common misconception about properties of matter

Heavy objects always sink while lighter objects always float. Picture a 500 ton boat made of steel floating on top of the water and this theory will not hold up. The ability to sink or float can be changed by increasing the amount of area the object takes up.

Energy

The ability to do work

Physical State

The classification of matter as a solid, a liquid, a gas

1st common misconception about properties of matter

The first misconception is that mass and weight are identical. Mass is a measurement of the amount of matter in an object while weight is a measurement of the amount of force gravity pulls down on an object. An object's weight will change when it travels to the moon but it's mass, amount of matter in it, will stay the same.

Property

a characteristic of a substance

Molecule

a particle of matter made of two or more atoms joined tightly together

Physical property

a property that can be observed, measured, or changed without changing the substance itself

Solid

a state of matter in which the substance has a definite shape and a definite volume

Liquid

a state of matter in which the substance has a definite volume but takes the shape of its container

Gas

a state of matter in which the substance takes both the shape and the volume of its container

Classify

group together based on similar traits

Celsius

measurement used in science for temperature

Mass

the material, or "stuff" that everything is made of

Condensation

the process of changing from a gas to a liquid

Evaporation

the process of changing from a liquid to a gas
