A hot air balloon has a volume of 2000 m3 when fully inflated and the air inside the balloon is at atmospheric pressure (101,000 Pa). What is the mass of hot air inside the balloon if its temperature is 120°C? (Assume a molecular weight of 28.8 g/mole for air, which is about 80% N2 and 20% O2.)

A recreational (open) hot air spherical balloon has a radius of 7.30 m when fully inflated. The total weight of the balloon, basket, ballast and pilot is 1710 N. When the balloon is released from its mooring, it moves upward and reached a terminal velocity of VT = 0.910 m/s. If the air resistance is given by Fair resistance = b VTwhere b = 2570 kg/s, what is the density in the hot air in the balloon? The density of...

An uninflated balloon of mass 6.00 x 10 kg has a volume of 7.10 x 10-2 m3 when fully inflated with a mixture of helium and hydrogen gas. You tie a long, heavy cord to the balloon and allow the balloon to float above a table. The length of cord lifted off the table is 283 mm, and the linear mass density of the cord is 0.260 kg/m. The mass densities are 1.286 kg/m3 for air, 0.179 kg/m3 for helium...

gas (density = 0.2 kg/m3) has a volume of 6 × 10–3 m3. If the
density of air is 1.3 kg/m3, what is the buoyant force exerted on
the balloon?
Test Bank, Question 29 A balloon inflated with helium gas (density = 0.2 kg/m3) has a volume of 6 x 10-3 m3. If the density of air is 1.3 kg/m3, what is the buoyant force exerted on the balloon? o0.01 N o0.08 N О 0.8N...

A recreational (open) hot air balloon (i.e., Pinside ≈ Poutside has a volume of 2339m3 when fully inflated. The total weight of the balloon body, basket, ballast and pilot is 1950.2N (439lb). How much less dense must the air in the balloon be than the surrounding atmosphere in order to keep the balloon floating level near the ground? (That is, give the difference of the densities.) Thank you for your help

A hot-air balloon is accelerating upward under the influence of two forces, its weight and the buoyant force. For simplicity, consider the weight to be only that of the hot air within the balloon, thus ignoring the balloon fabric and the basket. The hot air inside the balloon has a density of ρhot air = 0.76 kg/m3, and the density of the cool air outside is ρcool air = 1.29 kg/m3. What is the acceleration of the rising balloon?

A hot-air balloon is accelerating upward under the influence of two forces, its weight and the buoyant force. For simplicity, consider the weight to be only that of the hot air within the balloon, thus ignoring the balloon fabric and the basket. The hot air inside the balloon has a density of ρhot air = 0.95 kg/m3, and the density of the cool air outside is ρcool air = 1.29 kg/m3. What is the acceleration of the rising balloon?

A hot air balloon has a volume of 20 cubic meters. If the air inside is at a temperature of 70 degrees C and the outside air has a density of 1.17 kg/cubic meter, how much lift does the balloon generate? Hint: use 29.0 grams/mole of air.

A hot air balloon starts to take off when the temperature inside the balloon is 111 °C higher than the outside air. The pressure is the same inside and outside the balloon and there is a total of 2.50× 105 moles of air in the balloon. Assuming that the air density outside of the balloon is 1.20 kg/m3, what is the total mass of the balloon and its load? The answer is 2.73 × 103 kg. I am not sure...

You are helping to design a new hot air balloon for an upcoming regatta. Assuming that the temperature to which the air inside the balloon can be safely heated is 85 ˚C, what is the minimum volume require for the balloon if it is to lift a total weight (balloon plus passengers) for 250 kg. Take the outside air temperature to be 15 ˚C, the air pressure to be 1.00 bar, and make a reasonable assumption as to the composition...
