Somebody Help me....
I dun understand whats going on today...
I totally hate the facilitator...

Thanks eh..Ass...
The first thing my group members told me was " lets zhao (run)"
How ENCOURAGING eh...
Its not that i dun wanna do my work..How can i if i cant freaking understand...Sigh....
Even though i'am quite stressed up with my work, i'am still quite happy...
Why? Because of little things...
What little things? For me to know for you to find out..Wahahaha...
Oh ya, i watch step up yesterday..Its was good even though the actress was a little plump...She can dance pretty well too...
The music makes me wanan dance as well...
Actually i was like kinda dancing along as well..Lol..SHH....
I also went for audition for Love Me Please...
Its a short film about teenage love and confusion...

louis here: good luck to you, nick! :P I'am zhaoing now...
Yup, that was louis, one of the slackers...
Anyway back to the role,its gonna be quite challanging for me...Heex...If i get it that is...
Well, below is what i'am suppose to understand today...
Whoever can, respect....
Note the following facts which apply to the hypothetical “ideal” gas, which many real gases closely resemble under a wide range of conditions.
The pV content of a given number of molecules in an ideal gas at a given temperature is a fixed quantity. In this regard, it does not matter if the gas is methane or oxygen or a mixture. It is the number of molecules that affect the pV quantity.
The amount of pV grows proportionally with the absolute temperature for a given amount of molecules. Absolute temperature is expressed in Kelvin units (K).
One mole of gas is the amount of gas that contains 6.02 x 1023 molecules, which weighs its relative molecular mass in grams. One mole of hydrogen gas (H2) weighs two grams, and one mole of nitrogen gas (N2) weighs 28 grams.
When the temperature of a mole of gas is raised by 1 K, its pV content increases by 8.31 joules.
The increase in pV content for a mole of gas, when its temperature is raised by 1 K, is known as the universal gas constant, R = 8.31 J K-1 mol-1. The same quantity expressed for a single molecule is the Boltzmann constant k we encountered in an earlier activity (Natural Order).
Since there are 6.02 x 1023 molecules in one mole, we can calculate k as follows:
k = 8.31 ÷ (6.02 x 1023) = 1.381 x 10–23 J K-1
*Someone interpret that for me..Damn...*
