Hi kids, this is me again, ok, I'm going to send you this second video, and this second 00:00:00
video is to talk about matter in general, like in the first one, we're going to speak 00:00:06
about water, the states of water, ok? 00:00:10
The first thing, is water matter? 00:00:13
What do you think? 00:00:16
Of course, no? 00:00:17
We said the other day that everything is matter, everything around us is matter, in this case 00:00:18
water. 00:00:26
If I can tell you, ok, what is the situation, what is the state of water, is it solid, liquid 00:00:27
or gas? 00:00:32
Most of you are going to say, Oscar, it's liquid, it's liquid, and it's true, but water 00:00:33
cannot be only in a liquid state, water has three states, how is that possible? 00:00:37
Look, how can we find water in a solid state? 00:00:43
Very easy, if you think, do you have near you a situation where you find the water in 00:00:48
a solid state? 00:00:54
Of course, I saw you in the first video, this is water in solid, ok, this is ice, so when 00:00:55
you freeze the water, it's very cold, it's converted into solid, ok? 00:01:02
The regular liquid, the water in a liquid state, normally in nature we can find two 00:01:09
situations, we can find fresh water that we find in rivers, lakes, ponds, different places, 00:01:17
and salt water that we find in oceans and in seas, no? 00:01:24
Ok, and the third one, gas water, we have gas water, is it possible? 00:01:29
Ok, let's think, what happens in winter when you are having, it's very cold, and you are 00:01:36
having a very hot shower in the bathroom, what happens in the mirror, for example, when 00:01:42
you finish the shower, what happens in the mirror? 00:01:48
Ah, the mirror, it has something like, you cannot see in the mirror, because you have 00:01:51
something there, ok, this is the gaseous water, the gas water, that's why you can paint in 00:01:56
the mirror, ok, because it's very hot, and the water is converted into gas, ok? 00:02:02
Ok, but that is the three possible states, solid, liquid or gas, can we change from one 00:02:09
state to another state, of course, for example, so, I have here a piece of ice, ok, and in 00:02:17
a few minutes this ice is going to disappear, how is it possible that it disappears? 00:02:28
Ok, because in here, in this bedroom, it's hot, it's getting hot, and to be nice, you 00:02:33
have to be very very cold, so what happens to the ice? 00:02:40
The ice is melting, the reducing, the ice is melting and in a few minutes it's going 00:02:43
to convert it into water, ok, it's going to convert it into liquid water, ok, so if I 00:02:48
want to pass from solid to liquid, I have to hot the water, can I convert the liquid 00:02:54
water into gas water? 00:03:01
Yes, I already explained you, if you heat the water, so you put the hot water in the 00:03:02
shower, you are going to convert the water into gas, and this process is called evaporation, 00:03:08
the water evaporates, ok, that's why you can touch in the mirror, ok? 00:03:14
Ok, let's think the other way, can I convert gas water into liquid water? 00:03:19
Of course, of course, that's what happens, for example, well, in the same example, ok, 00:03:26
the hot water evaporates, but the thing that you can touch in the mirror is converted into 00:03:34
liquid, that's why you can touch it, because when you stop the shower, the hot water finishes, 00:03:40
ok, it starts to be, the bathroom is cold, and this is called condensation, this liquid 00:03:46
that is converted in the mirror is called condensation, or for example in the cars, 00:03:52
in winter as well, sometimes you touch the windows of the car and you have liquid, why? 00:03:57
Because the gas is getting cold and is converted into liquid water, ok? 00:04:03
Can we convert liquid water into ice? 00:04:12
Very easy, no? 00:04:15
If I put a piece of liquid gas, sorry, liquid water into the fridge, you can get ice, no? 00:04:16
What is the name of this? 00:04:24
Solidification. 00:04:26
So we have four different processes, melting, evaporation, condensation, when gas is converted 00:04:27
into liquid water, or solidification, when it changes the liquid water into solid, into 00:04:41
ice, ok? 00:04:50
Well, this is the stage of water, and I hope you understand, we are going to continue talking 00:04:52
about that in the next video conference, I hope you like it, and see you soon, ok? 00:04:59
Bye bye! 00:05:04
