Hello boys and girls, welcome to a new Natural Science Unit, Natural Science Unit 5, Lesson 2, States of Matter.
00:00:00
Remember that you have this worksheet in your notebook with the different states of matter and some experiments
00:00:10
to understand the shape and the volume of the different states of matter.
00:00:18
States of matter. There are three states of matter. Gas, liquid, and solid. Gases, liquids, and solids.
00:00:26
Let's understand the three states of matter using the example of water. We can find matter in three states.
00:00:43
vapor of water or water is thin, water in a liquid state, drops of water, and water
00:00:56
in a solid state as an ice cube or snow. But does this only happen or take place
00:01:06
with water no as a gas example we have natural gas as a liquid example we have
00:01:16
gas in the gas station or petroleum and as a solid example we have coal let's go
00:01:27
back to the example of water can water change from one state to another yes it
00:01:46
can. It's very important to bear in mind the different temperatures. When the temperature
00:01:54
of water reaches 100 Celsius degrees or above, it turns into a gas. When the temperature of water
00:02:02
is between 0 and 99 degrees Celsius degrees we can find it in the form of a
00:02:15
liquid and finally when the temperature of water decreases below 0 Celsius
00:02:25
degrees it turns into a solid the process of turning from gas to liquid
00:02:36
water cools down. The same thing happens in the process of turning from liquid to solid. However,
00:02:44
on the other hand, in the process of turning from solid to liquid and from liquid to gas,
00:02:55
the temperature of water heats up. The changes of the state of water have a name. When water
00:03:03
turns from gas into liquid, we call it condensation. When water changes from a
00:03:14
liquid to a solid, we call it solidification. When water changes from a
00:03:25
solid into a liquid, we call it melting. And finally, when water changes from
00:03:36
liquid to gas we call it evaporation. In class we became scientists and
00:03:45
experimented to understand the properties of the states of matter.
00:03:55
experiments 3, 4 and 5. In experiment 3, gases, we learned that gases expand to
00:04:01
fill the container. In experiment four, we learned that liquids take the shape of
00:04:14
the container. In experiment five, we learned that the shape of solids doesn't
00:04:22
change volume. Experiments six, seven, and eight. In experiment number six, we learned
00:04:32
that gases don't occupy the same space as they can expand and contract. In
00:04:49
experiment 7 we learned that liquids occupy the same space, equal space. In
00:05:00
experiment number 8 we learned that solids occupy the same space. Thank you
00:05:10
Thank you very much for listening, and goodbye.
