Gas and its characteristics
Hey! Did you know that there are many different types around us, such as solids, liquids, gases, etc. Today we’ll be talking about gas and its properties. Keep it very interesting and easy to understand!
What is gas?
Gas is one of the three main states in question (the other two are solids and liquids).
Example: Air is gas! When inhaling, it breathes air made up of various gases.
Gas does not have a fixed shape or a fixed size. They spread out to fill every place they were located. It fills balloons and accepts balloon shapes, but spreads everywhere when you bring out the air!
Can compress gas.
You can reduce the size by pushing or pushing the gas. This is called compression.
Example: Keep this in mind when pressing a balloon. The air inside is squeezed into a small room, reducing the balloons.
Gas has a lot of space
Gas is made up of small particles called molecules. These molecules are constantly moving around and there is plenty of space between them!
Example: Imagine a soccer ball full of air. The balls seem to be full, but in reality there is plenty of free space between the air molecules inside.
Gas can move quickly
gas molecules always move quickly! They move in all directions and sabotage things. This is a gas molecule that moves very quickly to get out of the can.
Therefore, if you skip gas (such as air or perfume smells) it will spread throughout the room. Anyone can smell it wherever you are in the room!
They simply spread out and fill in the room they are in.
Example: If you turn off the air from a balloon, it will not remain in the shape of a balloon. It floats in the air and spreads everywhere!
The gas can be hot or cold.
The temperature of the gas depends on how fast the molecules move.
Example: The hot air balloon rises as the air is heated by balloons. Hot air molecules move faster and take up more space, making balloons easier and whip them!
Gas pressure
Gas has pressure. That is, push the wall of the container where they are located. The more gas molecules, the faster you move, the higher the pressure! If there is too much pressure, the tires can be packed! Push things.
Fun activities to remember gas:
Activity:
Take balloons and blow the air. Keep the balloon and try to squeeze it with your hands. Note how difficult it is to squeeze it out as the air inside writes out (this is the pressure of the gas). Once you let go, the air will escape and the balloons will become smaller!
