What is hot air moving up an example of?
Hot air moving up is an example of convection, which is the transfer of heat through the movement of a fluid (in this case, air) due to differences in temperature and density.
Is air inside a hot air balloon an example of convection?
Yes, the air inside a hot air balloon heats up, becomes less dense, and rises. This is an example of convection, where heat is transferred through the movement of fluid (in this case, air).
Is buoyant force exerted by air also?
Yes, that is what makes hot air balloons and helium balloons float. Since air is far less dense than water, you need to displace far more air to get an object that floats on water to float in air. That's why hot air balloons are so huge.
What scientific principle explains hot air balloon flight?
The scientific principle that allows hot air balloons is the following.It's all in the name: hot air balloon. Hot air is blown into the opening at the bottom of the balloon. Because hot air is less dense than cold air, it rises. Since the balloon becomes filled with air that is less dense that that surrounding it, the balloon rises. If you want to make the hot air balloon rise faster, you have to either put less people in it or weigh it down less with less luggage or extra stuff.
What does buoyancy mean in science?
Buoyancy is the upward force exerted by a fluid (such as water or air) on an object immersed in it. This force is equal to the weight of the fluid displaced by the object, and it helps objects float or rise in the fluid. buoyancy is what allows boats to float and hot air balloons to rise.
Why does the upper radiator get hard?
the air/fluid gets hot and expands

Which line for cooling is the hot side vs return line top or bottom?
In a typical cooling system, the hot side is usually the top line, where heated fluid or air exits the system to be cooled. The return line, which brings the cooled fluid or air back into the system, is generally positioned at the bottom. This configuration allows for efficient heat exchange, as the hot fluid rises and the cooler fluid descends.

Why does your 2000 Ford Focus Wagon blow out stinking hot air when the air conditioner is on?
I attempted to refill the air-conditioning fluid and it had plenty of pressure... I'm not sure why the air won't get cold.
Why the hot air balloon needs hot air to make it rise?
Hot air balloons use hot air because hot air rises above cold air. The air inside the balloon is heated above the temperature of the air outside the balloon. The warmer air trapped inside the balloon then causes the balloon to float above the outside colder air.

What is the principle of fluid bed dryer?
Fluid bed dryer works on a principle of fluidization of the materials. In fluidization process, hot air or gas flow is introduced through the bed of solid particulates. This hot air will move upwards through the spaces between the particles and remove the moisture.
How does Archimedes principal work in hot air balloon?
Archimedes' principle states that the buoyant force on an object is equal to the weight of the fluid displaced by the object. In a hot air balloon, the heated air inside the balloon is less dense than the cooler air outside, creating a buoyant force that lifts the balloon. This principle allows the hot air balloon to float in the air by displacing enough air to lift its weight.
What are the 4 basic elements of heat exchanger?
The four basic elements of a heat exchanger are the hot fluid inlet, hot fluid outlet, cold fluid inlet, and cold fluid outlet. The hot fluid carries heat into the exchanger, transfers it to the cold fluid, and then exits the system. The cold fluid absorbs heat from the hot fluid and exits the system at a higher temperature.
