thanks its coming along well

Ok i need to know this for an essay I'm doign can someone explain to me the effect that changes in altitude pressure and temperature effect the gas inside the airship?

ohhh i see now sorry, I'm doing an essay on xenotransplantations at the moment so I'm a bit muddled with this, but i think i understand now thanks for you clarification.

yes so if the temperature was low enough would the mass of the gas be reduced to a point where it has a volume of nil?

I think I'm getting confused with the ideal gas theory which states "The state of an amount of gas is determined by its pressure, volume, and temperature." which would give the equation "pV = nRT" am i right so far?

The tests on gases show that the mass decreases so in theory should it not be able to reach nil?

Thanks for the advice i was wondering about the ranks and how accurate they were

oops i knew i forgot somthing i am applying for a medical course hoping to be a doctor.

I thought it was only in the gas theory that when a gas was cooled to absolute zero the mass would be nil and would in theory it would not exist, however even this was not proven and clearly should not happen so it is only an ideal gas that would? Cooling to absolute zero does require a lot...

I'm finishing my GCSES and now I have chosen my A level options (physics, chemistry, biology and maths) and now I'm wondering what universities I should be looking at, at the moment my main option is London UCL. Has anyone got some suggestions, and what is your opinion about London UCL?
