Hi, Ive a couple of questions. 1) Ideal gases expand according to temperature. But how quickly does it take for it to expand to its destined size? Lets say if I had 100 moles of Argon and heated it to 373kelvins. How long would it take for it to expand to it final size? 2) To what size will 100 moles of Argon heated to 373kelvins expand? How many litres? Cheers gang.
