Determine the volume (m^3) necessary to fill with hot air for a hot air balloon to lift a payload of 800 kg. Assume that the temperature inside the balloon is 99.0 C and the temperature outside is 20.0 C. Assume that the pressure (inside and out) is 1.00 atm and that the molar mass of air is 28.9 g/mol.

When fully inflated, a hot-air balloon has a volume of 1.6Ã105L at an average temperature of 383 K and 0.981 atm .

Assuming that air has an average molar mass of 29 g/mol, what is the density of the air in the hot-air balloon?

At constant pressure, density of gas is inversely proportional to its temperature. This is how hot air balloon is floating in air: burning fuel makes inside air temperature higher and density lower; low density air balloon float on high density regular air. What is the density of air in g/L at 68 degree C if the atmospheric pressure is 1.0 atm? The average molar mass of air is about 29 g/mol. Keep two decimal places for your answer.

A balloon is filled with hydrogen gas and produces the followingchemical reaction between iron and sulfuric acid: Fe(s) + H2SO4(aq)--> FeSO4 (aq) + H2(g). If the balloon had a volume of 4800cubic meters and was filled to a pressure of 1 atm at a temperatureof 0 degrees C, a) what mass of iron (in kg) and how many moles ofsulfuric acid were required to fill it? b) If the total mass thatcan be lifted by a balloon is equal to the difference between themass of gas in the balloon and the mass of air displaced by theballoon, how much mass could by lifted by this balloon and how muchmass could the same balloon lift if it was filled with helium atthe same pressure and temperature. c) using the barometric formulaP= P(initial)e^(-mgh/kt) to estimate the height to which theballoon with a payload of 1000kg can rise when filled withhydrogen. (The balloon will rise until its density equals that ofthe surrounding air) Assume the the temperature of the air does notchange with the altitude. Use an average molar mass for the airbased on 80% N2, 20% O2.
