The specific latent heat of vaporisation of a substance is the quantity of energy per unit mass required to change it at constant temperature from a liquid into a vapour

Boyle's law states that the volume of a fixed mass of gas is inversely proportional to the pressure exerted on it, provided the temperature is kept constant

For a fixed mass of an ideal gas at constant pressure, its volume V is proportional to the ideal gas temperature T. T will be a temperature in Kelvin

yeah, that;s exatly where i checked out of chemistry. i recall the boyles law thing as making my head hit the desk. hard.

The Avogadro constant N_A is 6.02 x 10²³ mol^-1

This comes under physics apparently, but its a bit too chemistryey or my liking...

One mole of any substance contains 6.02 x 10²³ particles

it had to have been chem in my school cause believe you me i never made it anywhere near physics

yep, the mioles, i remember not understanding any of that business. and the vectors.

 

ok, i;m having flashbacks now.

 

more than a little PTSD over this one...

moles... see i cant even type it

The Boltzmann constant is the gas constant for a singlr molecule.

 

1.3807 x 10^-23

I don't like it when when my physics is like chemistry :(

Oh, but that's all the definitions for that topic. Yay :)

your physics is chemistry.

 

did you not already take chemistry and was this not in the very first part of the text?

 

it was the first week of my chem class in G10.

 

vivid flashbacks. technicolor.

only class they ever let a scholarship kid withdraw from. and as far as i know, only english class they ever let anyone withdraw from.

 

i can be very stubborn about these things.

I did not take chemistry. In the compulsary bit we got a far as moles but that was it...

we were not given a choice. G9 bio, no prob. G10 chem, big prob. G11 physics was elective. i didn't elect, took AP english instead. G12 AP bio, no prob.

 

ok, these memories are way too clear now.

I didn't really like the pressure of having to write within a certain time limit in English....

But I'm off to learn some more definitions...

 

Back again later :)

ok i go soon and come right back

its too hot

I did not take chemistry. In the compulsary bit we got a far as moles but that was it...

 

moles are fun, physics and chemistry are rolled up in one here. what are moles again? something times by 10 to the 23

it's too wet.

 

weird about the snow in the south, cause people from two towns over got a mess of snow too. for some reason we didn't.

 

i sense a conspiracy.

its too hot

 

i was sweating a couple minutes ago, and its past 10 at night, its ridonkulous for this heat ot go on so long, my parents really have to fix some of these AC's

try cleaning the filters.
