AR only
BQ and R
CP, Q and R
DNone of these


There should be a limit on how much we can compress the gas.Are we confidently saying that 500 cm-cube volume can be filled in a 250 cm-cube cylinder?Well and if we have to, will the cylinder construction remain same?If all the gas in the world can be compressed then why do we have to use big tanks or tankers?
