Why do some materials require the addition of heat or hot air to aid the bending process?
Because they do
How do radiators work?
In most of them, hot water heats metal tubes they in turn radiate the heat. In electric ones, a small element heats tubes filled with oil and they radiate it. The process is known as convection.
Does cold air expand?
No. air actually contracts as it gets colder, while air expands as it gets warmer. For example, lightning is so hot, it causes the air to heat up intensly. This rise in temperature causes the air to expand so fast, that it breaks the sound barrier. This causes a sonic boom, and that is the thunder that you hear after lightning strikes.
Where can find a plentum?
A plenum is a space, usually an enlarged space in air handler ductwork (forced hot air heating systems). In the plenum the air can be heated, cooled, humidified or dehumidified before being redirected down smaller ducts for the final endusers. It is often the first space through which air, being drawn in through the filters, passes into the system.
What are the most common causes of fire in an engineering workshop?

What kinds of balloons are there?

What types of hot air balloons are there?
There are traditional hot air balloons, special-shaped hot air balloons (such as animals, objects, or characters), and solar-powered hot air balloons that use solar energy to heat the air inside.
Where in the atmosphere do hot air balloons float?
Hot air balloons float because hot air displaces cool air in the atmosphere
Why lighter than air balloons fly?
air balloons or hot air balloons fly because they fill with a very light type of air. The air is hot air.
What does thrust have to do with hot air balloons?
This may not help, but I didn't think it had ANYTHING to do with hot-air balloons...
Why were hot air balloons made in 1783?

How do hot air balloons stay in air?
hot air rises
How do hot air balloons produce lift?
Hot Air
Why do you think hot-air balloons can rise into the air?
Hot-air balloons can rise up into the air because hot air is lighter, allowing it to float up into the sky.
What are hot air balloons used for now a days?
Hot air balloons are now mostly used for leisure
Does a hot air balloon have helium inside it?
Hot air balloons do not use helium; they are typically filled with hot air. Helium is non-flammable and more commonly used in other types of balloons like weather balloons or party balloons. The hot air inside a hot air balloon is what allows it to rise and float.
