Temperature vs Dispprsion

H2O's (water) boiling point is 100c and its freezing point is 0c. In fact one of the characteristic properties of H2O are boiling and freezing point. When H2O evaporates it turns into water vapor. Water vapor is a type of gas. When you freeze water it turns into ice. Ice is a type of solid. If you put ice on its melting point you will get H2O once again.

Meteor that fell in Serbia

One week ago there was a meteor that crashed in Serbia! It was a big news in all the medias. A meteor is a natural object created in space. Meteors can be big or small. The meteor that appears in the sky, broke down into many little pieces, that eventualy became dust. It happened exactly next to a city called Prokuplje in centeral Serbia. When the meteor crashed it broke into many little pieces so if you are looking for a piece it will look like a small rock, but people can not see the difference between a regular one and the meteor's leftovers! When it was in space it was in liquid form and when it was landing it changed into solid form. Astronomers study meteors and they say that the from the moment the meteor comes in the earth's atmosphere, to the moment it burns, only a few seconds pass, so people can't see it at all. The fact that the meteor fell on Earth does not make any bad effects on people.

Earthquake in Serbia

There was an earthquake in Serbia last night at 01:57 a.m. It was located in a city called Kraljevo, and damaged a lot of houses. Sadly, there were two people who died. In the capital city Belgrade, which is about 200 km away from Kraljevo, there was a man who got scared of the earthquake and jumped from the first floor and injured himself. The rating of the earthquake was 5.5!!! That is one of the biggest earthquakes in the history of Serbia. I woke up in 01:50 a.m. and so did my grandma when 7 minutes later the earthquake appeared. All I saw shaking in our building was my bed! I raced to my grandma's room and we quickly got out of our apartment and waited to see if anything is going to happen like the building colapsing! After it finished in 01:58 we went back to our television to see if they broadcasted the earthquake. There were only movies so we went back to my room and sat there for 10 minutes to see if there will be another earthquake. Since there was no other one, we went back to sleeep.
