Matter
I'm going to tell you
00:00:01
I'm going to reveal
00:00:04
natural
00:00:06
okay
00:00:07
so matter is everything
00:00:09
is everything
00:00:12
around us
00:00:14
everything
00:00:15
and each type of matter is a substance
00:00:16
the substance
00:00:20
can be the light, the air
00:00:22
the sound, water
00:00:24
soil
00:00:25
we have some properties
00:00:27
Mass is the kilogram, the weight, and volume, how much it occupies, okay?
00:00:30
It's usually in literals.
00:00:36
The states of the matter, it can be solid, with a fixed shape, right?
00:00:38
Liquid, fixed in volume.
00:00:45
Gas, if it's in shape or volume, becomes part, okay?
00:00:48
The states of water, remember, there is a system that we need to bring.
00:00:54
states of water. Solid, we can find it as snow
00:00:59
or ice. And liquid, in rivers and oceans and lakes
00:01:02
and ponds. And the gas, we can find it in geysers,
00:01:06
water viper, and clouds, okay?
00:01:10
And right after that, the changes of state of water
00:01:15
can be from condensation. Remember that they are from gas
00:01:18
to liquid, okay?
00:01:22
Melting is when we have something solid and it turns into liquid.
00:01:25
Evaporation is when something is liquid and later it turns into gas, like water vapor.
00:01:35
Okay, solidification is liquid, water, we put it in the fridge, we freeze it, right, in the refrigerator, and it turns into solid.
00:01:45
Okay?
00:02:02
The substances that we talked before, remember they can be pure, so only one substance, or mischievous, like some of them together.
00:02:05
Is there any doubt?
00:02:14
No?
00:02:15
No?
00:02:16
No.
00:02:17
No?
00:02:18
You don't have to go there now?
00:02:18
No.
00:02:19
Yes or no?
00:02:20
No?
00:02:20
No?
