Matter

What is Matter?

Matter makes up anything with mass and volume. But what is mass and volume?

 

Properties of Matter

  1. Mass
    • Mass is the amount of matter in an object.
    • Mass is measured in grams and kilograms, and can be found by using a pan balance
  2. Weight
    • Weight is how strong gravity pulls an object
    • Weight can be measured in Newtons, or in the USA pounds and ounces
  3. Volume
    • Volume is the amount of space matter takes up
    • It is measured in milliliters for liquids and cm solids

What is density?

Density is the amount of matter per cm3. It is different from the mass because mass is the total amount of matter in an object. If the density of a small box is more than the mass of the bigger box, the bigger box could still have more matter because the box is bigger and mass is the amount of matter in the entire object. The amount of matter only for a cm3 of the box is the density.

 

States of Matter

  • Solid
    • The particles in a solid are packed together and do not have any place to move around. They just vibrate.
    • A solid stays in a fixed shape without changing it unless a chemical change is made to turn the solid into a liquid.
  • Liquid
    • The particles in a liquid are not packed together tightly, but they are still close together
    • A liquid can take shape of any object, for example a container. If you add a liquid into the container, it will take that shape
    • The shape of a liquid can be changed
  • Gas
    • The particles in a gas are not close together and move around freely.
    • A gas has no definite shape of volume

The fourth state of Matter

There is another state of matter that most people don’t know about. It is called plasma. Plasma is made when an unreactive gas like neon, argon, krypton, and more is heated to extreme temperatures. An example of plasma is the neon lights outside of shops.
