Pardon Me!

  • Learning Intention: Using Notability take notes (dot points, arrows, diagrams, images) about gas. Then send your work to me via Showbie.
  • GAS
  • Like solids and liquids, gas is a common state of matter.

  • Image result for examples of gas for kids
  • Pure gases are made up of just one atom. Neon is an example of a pure gas.

  • Elemental gases are made up of two or more of the same atoms joined together.Hydrogen gas (H2) is an example an elemental gas.

  • Compound gases contain a combination of different atoms. Carbon monoxide (CO) is an example of a compound gas.

  • The air we breathe here on Earth is made up of different gases. It contains around 78% nitrogen, 21% oxygen, 1% argon and a small amount of other gases.

  • Natural gas contains mostly methane, it is used as a fuel to generate electricity and is common in the home where it can be used for heating, cooking and other purposes.

  • Gas pressure is measured in pascals.

  • The helium balloons you get at parties and carnivals float because helium is lighter than the air surrounding it.

  • Noble gases are a group of chemical elements that are very stable under normal conditions. Naturally occurring noble gases include helium, neon, argon, krypton, xenon and radon.

  • The ozone layer that protects Earth from the Sun’s potentially damaging UV light is made up of ozone (O3), an oxygen allotrope containing 3 oxygen atoms bound together.

  • Nitrous oxide (N20) is a gas with interesting properties that allow it to be used in a variety of different ways, these include as an anesthetic in hospitals (you may have heard it referred to as laughing gas) and to increase the power of engines in motor racing (often called nitrous or just NOS).

  1. I learnt that particles in gases are very spread out. There are two types of gases that the earths air is made up of: oxygen and nitrogen.

  2. I learned that there are lots of different types of of gases and that the helium in balloons can make balloons go up because the gass in helium is lighter than air.

  3. This week I learnt:
    ~ That some gases can be touched
    ~That the air around us has mostly nitrogen 78% and 21% oxygen and a small amount of argon – 1%
    (Love the title :] )

  4. I learned that there are lots of different types of gases around us like helium, nitrogen, oxygen and hidrogyn

  5. I learnt about what makes up the air and how much percent of it there is.
    It will help me learn faster in the future.
