A 10L cylinder has helium at 8 atm and 32^@C. How many balloons of 2L each at 2atm and 32^@C can be filled with the gas available from the cylinder.

A 10L cylinder has helium at 8 atm and 32^@C. How many balloons of 2L

1.	A 10L cylinder has helium at 8 atm and 32^@C. How many balloons of 2L each at 2atm and 32^@C can be filled with the gas available from the cylinder.
Answer» Solution :The PVof balloon ` = 2 xx 2 = 4` lit-ATM Gas from the cylinder is available to fill in the BALLOONS, until pressureof gas in cylinder drops from 8 atm to 2 atm. The PV of helium available ` = 10 xx (8-2) = 60` lit-atm Number of balloons filled ` = ("PV of the gas available")/("PV of the balloon")= (60)/(4) = 15`
