AS levels is the first year of Alevels. So those taking Alevels will have to give an exam in the first year. The second year is Alevels for which u give another exam.
I have taken A levels. So I have my AS same time next year and A levels in November next year.(i'm doing 18months and not 2 full years). So I get six months to prepare for entrance exams here

--- End quote ---
for fractional distillation was parrafin..because it says used in jet or something..

we had here in kuwait an exhibition where all the universities were there..all of them wanted A levels...3 of them...and not less than a B!! :o

Different country different system. What happens if you decide you cant stand physics?

There is nothing got to do with it being heavier or abundant. They asked what makes it suitable for filament lamps.
Helium is also abundant if u guys don't know. It is used in weather balloons and in scuba diving(80%helium and 20%oxygen mixture, although oxygen is more abundant) .
The reason why argon is used in filament bulbs is because the metal filament will not burn in Argon and it reduces evaporation of the metal filament.

i know im a bit late for this topic
i was out all day
anyways i wanted to say dat my dad is a chemical engineer and he sed being abundant is da probably da ryt answer
cos it is and dey dnt expect us to know all da properties of argon as opposed to helium
bt they do expect us to knw da composition of air and it contains more argon
and i quoted this to say dat you shud compare da number of weather baloons and scuba diving kits to light bulbs
