| 00:0-1 | mm . Hello friends . Welcome to a new Happy | |
| 00:09 | Learning video . You all know that Matter is what | |
| 00:14 | things are made of and that it possesses two fundamental | |
| 00:19 | properties . It has mass , which is the quantity | |
| 00:23 | of matter that it has and volume , which is | |
| 00:27 | a space it occupies . Well today we're going to | |
| 00:32 | learn about the states that matter can be in matter | |
| 00:38 | can be in three states solid form , liquid form | |
| 00:43 | and gas form . Each one of these has its | |
| 00:47 | own characteristics . Let's get to know them . Solid | |
| 00:52 | state is characterized by having a fixed volume and size | |
| 00:58 | . Although in some cases we can change its size | |
| 01:02 | like with plasticine or clay . In these cases they | |
| 01:06 | are malleable solids liquid state is characterized by having a | |
| 01:14 | fixed volume and variable size liquids take the containers shape | |
| 01:23 | like this . Glass or jug . Gas state is | |
| 01:29 | characterized by having a variable volume and size in the | |
| 01:34 | same way that liquids take the shape of the container | |
| 01:37 | holding them . But gas is always occupy the full | |
| 01:41 | volume of the container . Now we know about the | |
| 01:48 | three states of matter . But do you know how | |
| 01:52 | we can change from one state to another ? Yeah | |
| 01:57 | . Yeah . Changes in state happened after cooling or | |
| 02:02 | heating matter . And there are different types melting solidification | |
| 02:09 | , evaporation and condensation melting happens when matter changes from | |
| 02:16 | its solid to liquid form and happens after rising temperature | |
| 02:22 | . When we heat an ice cube or leave it | |
| 02:25 | at room temperature , it melts and changes from solid | |
| 02:29 | to liquid . Solid edification is the opposite from melting | |
| 02:34 | matter changes from liquid to solid form . It happens | |
| 02:40 | when we put water in the freezer and it turns | |
| 02:44 | into ice , it goes from liquid to solid . | |
| 02:49 | Evaporation is when matter changes from liquid to gas . | |
| 02:56 | After liquids are heated . For example when we boil | |
| 03:00 | water , it turns into water vapor , it turns | |
| 03:04 | from liquid to gas . Condensation is a step from | |
| 03:09 | gas to liquid and happens when matter in gas states | |
| 03:14 | is cooled . Have you ever noticed that when we | |
| 03:18 | get steamy windows or mirrors , water droplets appear . | |
| 03:23 | It's produced when water vapor touches a cold surface . | |
| 03:27 | In that same moment water vapor cools and turns into | |
| 03:31 | liquid . Easy . Huh ? Well , now we | |
| 03:37 | know the states of Matter . Goodbye friends and don't | |
| 03:42 | forget to describe to happy learning tv . Yeah . |
