Okay, it's chapter 9 now 8)
AREEEE YOU READYYYYYYYY KIDS?!
Physics is good(y) I like physics.
I can even READ physics with a swollen eye :B

Firstly we're going to touch on WHAT IS INTERNAL ENERGY!

WHAT IS INTERNAL ENERGY.
Internal energy is the amount of energy needed to raise the temperature.


Ok, that's number one, easy? Easy peasy 8)
(btw my eye is still like a fishball, i hate my eye yuck)

Secondly, Melting and Solidification!

Melting: From a solid state to a liquid state.
Solidification: from a liquid state to a solid state.

OKAY THAT WAS EASY! RIGHT?!?!?!?!?!?!?! 8)

Next, we've.. Boiling and Condensation.

Boiling: liquid changing to vapour.

It occurs at a fixed temperature, quick in process, takes place throughout the liquid,
bubbles are formed, temperature remains constant, thermal energy supplied by energy source.




Condensation: It is the reverse of boiling 8)

Lastly, we've Evaporation!

It is similiar to boiling, it is a process where liquid is changed into gaseous state.

However it's different as it has different conditions than boiling.

1. Occurs at ANY temperature.
2. Slowwwwwwwwwwwwwww.
3. Takes place only at the liquid surface.
4. No bubble formed.
5. Temperature varies.
6. Thermal energy supplied by surroundings.

That's all! ;) See! Physics is not as bad as you think!
Now... videos! Watch 2 boost your physics yum yum intelligence(y) !
