What is the parachute valve cord for in a hot air balloon?
The parachute valve cord in a hot air balloon is used to control the opening and closing of the parachute valve at the top of the envelope. This valve helps release hot air to control the altitude of the balloon by allowing the air to escape. The cord is pulled to open the valve, releasing hot air, and released to close it.
Why does pulling the cord have this effect hot air balloon?
Pulling the cord on a hot air balloon opens a valve that releases hot air from the balloon, causing it to sink. By releasing hot air, the balloon becomes less buoyant and starts descending. This allows the pilot to control the balloon's altitude and descend to the desired landing spot.
How is a parachute different from a hot air balloon?
Its a fairly large difference. A hot air balloon is meant for multiple people and it propels itself and maintains a high altitude by burning gas, making it float. A parachute is just meant for slowing someone's speed while falling
Why does hot air balloons float?
To put it simply, hot air balloons rise due to heat produced by the burning of propane, the heat travels up through the balloon's valve into the balloon itself (the envelope) and up to the parachute valve. Since heat rises, the hot air balloon its self rises. Better answer: a boat floats on water because it weighs less than the water it replaces. likewise, a hot air balloon floats, because the weight of the total balloon + hot air is less then the volume of cold air it replaces. Air has a weight too, but normally you don't notice.
How does thrust act on a parachute?
Thrust does not act on a parachute. A parachute experiences air resistance, which is a force that opposes the downward motion of the parachute and slows its descent. This air resistance allows the parachute to safely decelerate a falling object.

What is the bottom of a parachute?
a person or on a hot air balloon, a basket
What is the parachute valve at the top of a hot air balloon is used for?
The parachute valve at the top of a hot air balloon is used to release hot air from the envelope to control the descent rate. By opening the parachute valve, the pilot can allow hot air to escape, which cools the air inside the balloon and causes it to descend. This helps in maneuvering and landing the balloon safely.
Name something that needs to travel slowly through air how does it manage this?
A skydiver - he uses a parachute that slows him down as a result of air resistance acting on the surface of the parachute

Who was the artist that sketched a pyramid parachute 300 years before it was invented?
hot air balloon
Why does heat makes the parachute fly?
heat makes a parachute fly because when hot air goes into a balloon shape it blows up and then lifts into the air it acts like helium o yeahhhh
Can you make a parachute from a balloon?
Physically it is impossible. The air would rush through the bottom of the balloon so quickly that it would fill up fast and pop quickly.
Is the parachute an improvement over previous technology?
The idea of the parachute appears to go back to Leonardo Da Vinci, but human carrying ones were not made until the hot air balloon in the 1700s.
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.
