What We've Learnt....

Today we learnt a lot of things..
Not sure where to start..
Hm...
We learn about Riveting..
Melting...

Boiling..
Freezing...
Condensation...
Riveting...
Rivet is a permanent mechanical fastener.
It tightens two metals together ..
A cool rivet:
2 metal plates tighten together when
rivet contracts...

Melting**
+ Change of state from solid to liquid without a change
in temperature....
E.G. Ice melts at 0 degree celcius........
Condensation.....
Condensation is the change of the physical state of aggregation (or simply state) of matter from gaseous phase into liquid phase.

Boiling........

Boiling, a type of phase transition, is the rapid vaporization of a liquid, which typically occurs when a liquid is heated to its boiling point, the temperature at which the vapor pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding environmental pressure.

Freezing............
Freezing or solidification is the process in which a liquid turns into a solid when cold enough. Melting, the process of turning a solid to a liquid, is almost the exact opposite of freezing.
All known liquids freezes and their temperature has fixed points which is 0 degree celcius....
Okay, got to go now..
Toodlez...
But wait!!!
Got pics for u guys to c..
