Question

CH 06 HW Exercise 6.44 C)11 of 15 Part A in order for a gas filed bałoon to rise in a, the density of the gas in the baloon must be less than that of alr a molar mass of 28 96 g/mol Determine the minimum temperature to which the balloan filled with axygen at 1 atzm would have to be heated before it could begin to rise in al dgnore the mass of the balloon iself) air at 25 C and 1 atm to have incorrect, one attempt remaining: Try Again the srong numbec of significant figures ma Next >

Answer 1

We know that for given d = p m/R T density of air (d) = 1atm times 28.96 g/mol/0.08314L atm/mol kv (25 + 273) k = 1.17 g/L inorder to rise the ballon in the air it should have density approximately Equal to the density of air Density of O_2 in the ballon = 1 atm times 32/mol/0.08314 L atm/mol k.T 1.17 = 32/0.08314 times T (9.72 times 10^-2) T = 32 T = 328.96 K T = 55.96 degree C
