Question

A balloon containing an ideal gas has a volume of $$l0$$ litre and temperature of $$l7o$$. If it is heated slowly to $$75$$"C, the work done by the gas inside the balloon is (neglect$$ elasticity of the balloon and take atmospheric pressure as $$l05$$ $$Pa)

Infinity Learn · Accepted Answer

Since elasticity of balloon is negligible, pressure inside balloon pressure outside balloon $$=$$ Patm∴ W $$=$$ Patm∆V     Vin $$=$$ $$10$$ litre     $$VinTin=$$ VfinTfin ⇒ Vfinal $$=$$ (VinTfinalTin)litre$$⇒W $$=$$ $$PatmVin(TfinalTin-1)⇒ $$105$$×$$10-2(58290)$$ $$=$$ $$200$$ J

A balloon containing an ideal gas has a volume of l0 litre and temperature of $l 7^{o}$ . If it is heated slowly to 75"C, the work done by the gas inside the balloon is (neglect elasticity of the balloon and take atmospheric pressure as $l 0^{5}$ Pa)
