However, the temperature does not need to be exactly 100°C. What is a from and safe range of temperatures? This range may vary with the size and (decorative) shape of the bailoon. All balloons have a temperature gauge in the crown. Suppose...

At wind speeds above 1000 centimeters per second (cm/sec), significant sand-moving events begin to occur. Wind speeds below 1000 cm/sec deposit sand and wind speeds above 1000 cm/sec move sand to new locations. The cyclic nature of wind and moving sand determines the shape and location of large dunes. At a test site, the prevailing direction of the wind did not change noticeably. However, the velocity did change. Sixty-three wind speed readings gave an average velocity of x = 1075...

b. A hot air balloon has a volume of 2000 m3 when fully inflated, and the air inside the balloon is always at atmospheric pressure because of the large opening used to fill the balloon and heat the air inside it. What's 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.) 1790 kg 5850 kg 62.0 kg 203 kg

The air in a hot-air balloon at 775 torr is heated from 23.0°C to 25.0°C. Assuming that the moles of air and the pressure remains constant, what is the density of the air at each temperature? (The average molar mass of air is 29.0 g/mol) Density at 23.0°C _____ g/L density at 25.0°C _____ g/L

Constants Part C Hot air balloons float in the air because of the difference in density between cold and hot air. Consider a balloon in which the mass of the pilot basket together with the mass of the balloon fabric and other equipment is mb. The volume of the hot air inside the balloon is Vi and the volume of the basket, fabric, and other equipment is V2. The absolute temperature of the cold air outside the balloon is T...

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...
