How does a hot air balloon return to Earth's surface?
A hot air balloon comes down when less lift is provided by reducing balloon air temperature to control descent.
How does a balloon pilot control BOTH acsent and descent of a balloon?
A balloon pilot controls ascent by heating the air inside the balloon with a burner and descent by allowing the air to cool or venting it.
Which can be steered a balloon or a dirigible?
Definitely a dirigible because a hot air balloon cannot be steered because the wind carries it. A dirigible is an air ship and has control systems.
Why do hot air balloons fly at high altitudes?
Hot air balloons can fly at almost any altitude they choose. The height of the balloon flight is determined primarily by the pilot. Most balloon flights are tourist sightseeing flights or just fun flying by sport pilots. These flights are typically performed between 500 and 2000 feet above the ground. Also balloons must comply with the air traffic control regulations which limit where and how high balloons may fly unless they carry special navigation and communication equipment. On November 26, 2005, Vijaypat Singhania set the world altitude record for highest hot air balloon flight, reaching 21,027 meters (68,986 feet) above sea level. This flight was done in India under special permission from Indian authorities using a specially designed hot air balloon. Don Boyer Hot Air Balloon Pilot New Mexico, USA
How does a hot air balloon go sideways?
It does but you can't control it. The wind controls all it's movements. The only thing we can control is going up and down.
How does a balloonist control the fall and rise?
A balloonist controls the balloon's altitude by adjusting the temperature inside the envelope. By heating the air with burners, the balloon rises, and by allowing the air to cool, the balloon descends. Additionally, the balloonist can control horizontal movement by finding winds blowing in different directions at varying altitudes.
What is a stratospher?
the stratosphere is in control of raising the altitude in the temperature. And is the secon layer of gas in the atmosphere.
How does a hot air balloon return to Earth's surface?
A hot air balloon comes down when less lift is provided by reducing balloon air temperature to control descent.
Why is important to control variables in an experiment?
So that you can know what is the manipulating variable, the controlling variable, and the responding variable! To control the variables!
How do you land a hotair balloon?
Well All hot air balloons have a variable release valve in the top of the balloon which the pilot can use to control the altitude of the balloon..This valve when opened to a certain point allows hot air to slowly escape from the top of the balloon and the balloon will slowly decend,the exchange is controlled so the balloon maintains its size...by use of the release valve and the burners the pilot can control the rate of decent to a nice soft landing....The release valve is also used to quickly deflate the ballon once it has landed...
How does a balloon pilot use density to control the altitude of a balloon?
the pilot heats the air stored in the balloon with a large flame the hotter it gets the higher it goes because the heat changes the density to make it go up or down if the pilot decreases the size of the flame the hot air lowers because the smaller flame has less heat giving it a higher volume, but the air stays the same thus making it lower
How does a balloon pilot control BOTH acsent and descent of a balloon?
A balloon pilot controls ascent by heating the air inside the balloon with a burner and descent by allowing the air to cool or venting it.
Why does a hot air balloon need ballast?
Hot air balloons DON'T need any ballast. However gas balloons which get their lift from lighter-than-air gases, typically helium or hydrogen, do need ballast. The ballast allows the pilot to control the altitude at which the balloon flies. To gain altitude the pilot releases some ballast or vents out some gas to descend. During flight some gas will be lost through natural losses through the material of the gas envelope and the pilot counters the loss of lift by releasing ballast to maintain the altitude he wants. On long distance flights the variation between night and day time temperatures affects the amount of lift the gas exerts of the balloon. This requires further adjustment of gas venting or release of ballast to maintain the desired altitude.
What does a controlled test mean?
The environment is CONTROLLED. This can be many things, Temperature, humidity, altitude, = pressure. It depends on what you are testing and why. If you are testing a car tire you will control the pressure and the type of surface you are testing it on. Rex

How do modern hot air balloons fly?
They fly by putting heated air into the base, usually from a propane fueled heater - much like a large blowtorch. When the total mass of the balloon is less than an equivalent volume of unheated air - it will try to fly. Of course the mass of the balloon includes not only the expanded air inside the balloon, but the balloon itself, the heating system, the basket and occupants, and any ballast. To raise or lower the balloon, more heat is added, or hot air is vented from controllable openings near the top of the balloon. Some very limited directional control is available, since with higher altitudes the wind direction changes, and varying the altitude will change the direction of the balloon's travel.
Which can be steered a balloon or a dirigible?
Definitely a dirigible because a hot air balloon cannot be steered because the wind carries it. A dirigible is an air ship and has control systems.
