What is the name of the sand bag dropped for a air balloon?
I believe the word you're looking for is Ballast.
How can a pilot reverse the direction of a balloon that is rising?
A pilot can reverse the direction of a rising balloon by adjusting its altitude control. This is typically done by releasing some of the buoyant gas, such as helium or hot air, allowing the balloon to descend. Alternatively, if the balloon is equipped with a ballast system, the pilot can drop weight to accelerate the descent. By managing these factors, the pilot can effectively change the balloon's vertical movement.
How does a hot air balloon gain altitude?
Altitude is controlled by the propane burner and the parachute valve. The parachute valve is an opening at the top of the balloon envelope. When closed, it traps hot air from the burner inside the balloon, making the hot air balloon rise. When opened, it allows hot air to escape, and the hot air balloon descends. The reason a hot air ballon rises is because the density of the balloon is less than the density of the surrounding air. Its the same thing as "why does a boat float". In the case of the balloon, the operator modulates the flame on and off to maintain the desired altitude - increase the flame, and the balloon goes up - decrease or shut off the flame, and the balloon goes down. A better metaphor to a boat is a submarine - add ballast and the submarine goes down - blow ballast and the submarine goes up.
What could the crew of a hot air ballon do to raise the balloon above some trees?
To raise the hot air balloon above some trees, the crew can increase the temperature of the air inside the balloon using the burner, which will create more lift. They should also ensure that the balloon is not carrying any unnecessary weight. If needed, the crew can release some ballast to lighten the load, allowing the balloon to ascend more easily. Additionally, they should monitor wind patterns to find a safe ascent path.
How does hot and cold air have an effect on an balloon?
If there is warm air in the balloon, cooler air makes the balloon rise and if there is cold air in the balloon warmer air makes the balloon fall.

How much ballast is generally used on a typical hot air balloon ride?
The ballast is determined by how many passengers are present on each trip and the amount of lift that the balloon provides at takeoff. So if there's a lot of people onboard less ballast is needed and vice versa. In general it's less than 300lbs.
What is the difference between a ballast and anchor?
A ballast is a weight used to stabilize a ship or other structure, helping it maintain balance and stability. An anchor, on the other hand, is a device that is dropped to the sea bottom to prevent a ship from drifting away, providing a temporary hold or mooring. Essentially, a ballast keeps a vessel stable, while an anchor keeps it in place.
About how much ballast does a tour hot air balloon have onboard?
The amount of ballast a tour hot air ballon would need is about six bags of sand. You will need engough support to hold the big group of passengers.
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.
Does a gas balloon accelerate?
When a balloon ascends, it undergoes acceleration. This is in spite of the forces like gravity that acts on it. The acceleration of the balloon can be calculated using Newton's second law of physics.

Will a helium balloon deflate as it floats skyward?
The opposite problem occurs the gas will expand as the balloon rises and it will explode from the pressure. Blimps and manned balloons avoid this hazard with maneuvering vents and ballast tanks- akin to those on subs.
If the air balloon needs to carry more people. how can the pilot get the heavier load off the ground?
To lift a heavier load off the ground, the pilot can increase the temperature of the air inside the balloon by using the burner. As the air inside the balloon heats up, it becomes less dense than the cooler air outside, creating lift and enabling the balloon to rise with the heavier load. Additionally, the pilot can adjust the amount of ballast on board to help control the ascent.
Why do hot air balloons have sandbags?
A hot air balloon needs to be slightly negatively bouyant. If a particular design can lift 1000lbs, an ideal flight weight might be 900 lbs so that, in the event of a burner failure, the balloon will slowly descend. If the payload for a given flight is only 600lbs (fuel, pilot, passengers) then 300 lbs of ballast (sandbags) will be needed to keep the bouyancy in the correct range. ------------------------------------------------------------------------------------------------ Sandbags or other ballast is used mostly for helium balloons, not hot air balloons. The rate of descent of a hot air balloon is controlled by the time the burners are burning. If it is going down too fast, you burn longer. You may have two burners but if you lose one, the other one can keep the balloon aloft. they are always much larger than needed. The design weight is based upon the volume of the balloon and a particular temperture of the air in the balloon which must be below the melting point of the fabric. Typically you don't need ballast to adjust payload in a hot air balloon. IN a helium balloon, the only way you can go back up after starting a descent (by dumping helium) is the drop some weight. So ballast would be helpful with helium balloons.
What is ballast?
You put on/in a ship or raft etc. That makes it float better or makes in more stable
