The focus of the video is about the three states of matter which are Solid, Liquid, and Gas.
There are different states of matter, some of which goes up to 22 types of matter.
Solid, Liquid, Gas, and Plasma are the four fundamental states of matter.
Solid - solid is a substance or object that is solid rather than liquid or fluid.
A substance which exists in the solid-state.
Liquid - liquid is a substance that flows freely but is of constant volume, having a consistency like that of water or oil.
A liquid can flow and does not have a specific shape like a solid. Instead, a liquid conforms to the shape of the container in which it is held.
Gas - gas is a substance that is in a gaseous, or vaporous, state of matter.
A gas has no fixed shape or volume.
Gases can be made up of a single element, such as hydrogen gas (H2), a compound, such as carbon dioxide (CO2), or a mixture of several gases, such as air.
Gas is made up of atoms, tiny particles that make up molecules, and molecules that move faster and further away as compared to other states of matter, which enables gas to fill a container evenly.
The teacher in the video asked the viewers "What is sunlight?"
And I answered "gas?"
But the answer was that it was not applicable, because sunlight is not any of those types of matter, it is an example of energy, such as.
-Sunlight/light
-Sound
-Temperature
Even though they occupy space, they still don't have mass.
Therefore, light, sound, and temperature are examples of energy, and not matter.
What is mass?
(These are my simplified answers)
•Mass - how much you have inside.
(you know, atoms?)
•Weight - how heavy you are due to the gravitational pull.
•Volume - how much things you added, like litters (L), millilitre (ml), etc. etc. Like for example, how many pens you have in you're bag or pocket.
•Density - how compact or concentrated something is.
Concentrated/Concentration - is a substance or solution presenting in a high proportion relative to other substance.
(Or contained or existing or happening together in a small or narrow space or area.)
Mass and weight are two different things. (I still don't understand)
Mass - is something that takes space and how many there are or. Something....
Weight - is how heavy you are due to the gravitational pull.
The teacher in the video talks about how there are different scales rather than two of those being the same, the first one is balance, it is for mass, and the other is scale, taking your scale.
