Two hot-air balloons have just been launched. They have equal volume and pressure, but balloon A has a more efficient heating system, so the gas in balloon A is at a higher temperature than the gas in balloon B. (a) Which balloon holds gas with a greater density, balloon A or balloon B? (b) Support your answer. (Assume a volume of 1.00 m3 and a pressure of 1.00 atm for both balloons. Also assume an operating temperature of 115C for balloon A and an operating temperature of 102C for balloon B.) approx. density in balloon A mol/L approx. density in balloon B mol/L (c) Which balloon do you think will rise faster
