Answer number 11 10. Gas from a bottle of compressed helium is used to inflate an inelastic flexibleballoon, originally folded completely flat to a volume of 0.5 m3. If the barometerreads 760 mm Hg, what is the amount of work done upon the atmosphere by theballoon?[Ans.50.66 kJ]11. A rubber balloon (flexible) is to be filled with hydrogen from a storage cylinder,which contains hydrogen at 5 bar pressure until it has a volume of 1 m3. Theatmospheric pressure may be taken as 1.013 × 105 N/m². Determine the workdone by the system comprising the hydrogen initially in the bottle.[Ans.101.3 kJ]
