Why is a hot air balloon an example of conduction?
A hot air balloon is not an example of conduction because conduction is the transfer of heat through direct contact between particles in a material. In a hot air balloon, heat is transferred through convection as the heated air rises and displaces the cooler air.
Give an experiment to show that air a bad conductor of heat?
You can conduct an experiment by heating a metal rod at one end and touching it to a balloon filled with air. The balloon will not pop immediately because air is a poor conductor of heat, so the heat does not transfer quickly enough to cause the balloon to burst.
What is the primary mode of heat transfer in a compartment prior to flash over?
The primary mode of heat transfer in a compartment prior to flashover is typically through convection. As the temperature rises, hot air and gases transfer heat to the surrounding surfaces through convection currents. Radiation and conduction also contribute to heat transfer, but convection is the dominant mode in this stage.
What is the mode of heat transfer from a room heater?
The mode of heat transfer from a room heater is convection. This process involves the transfer of heat through the movement of fluids or gases, such as air. The heater warms the air in the room, causing it to rise and circulate, thus heating the surrounding space.
When a hair dryer heats a balloon and the air inside it the balloon expands is radiation convection or conduction?
it is radiation but is also convection. thanks for the time to read it

What are the types of heat transfers?
Conduction: Transfer of heat in solids Convection: Transfer of heat in liquid and gases (convection currents are the motion of which the heat travels in, see hot air balloon's) Radiation: Transfer of heat through vacuum (space i.e no particles)
What causes heat in air molecules in a hot air balloon to carry thermal energy to the top of the balloon?
As the air inside the balloon is heated, its molecules gain kinetic energy and move faster. The hotter air molecules are less dense and rise to the top of the balloon due to convection currents. This results in a temperature difference between the top and bottom of the balloon, allowing heat energy to transfer upwards.
What energy changes take place when a hot air balloon operates?
A hot air balloon operates through the transfer of energy, primarily from burning fuel to heat the air inside the balloon. As the air inside the balloon gets heated, it becomes less dense and rises, creating lift. This process involves converting chemical energy from the fuel into heat energy and potential energy as the balloon gains altitude.
In which mode of transfer of heat does the medium not get heated up?
Infrared radiations. They do not require any medium. So they don't heat any medium. They don't even heat the air through which they pass.
Would a hot air balloon pilot heat or cool the air in the balloon to make it rise?
He would heat it.
What energy transfer is a hot air balloon?
A hot air balloon demonstrates the transfer of thermal energy, as the burner heats the air inside the balloon, causing it to become less dense and rise. This creates lift, allowing the balloon to float in the cooler air above.
Why does a balloon with an aluminium coating take longer to shrink than a rubber balloon?
A balloon with an aluminum coating takes longer to shrink because aluminum is a good insulator of heat, which slows down the transfer of heat from the surrounding air to the balloon. This insulation property helps retain the heat inside the balloon, making it take longer to cool down and shrink compared to a rubber balloon.
