When Heated air molecules in a hot air balloon soon carry thermal energy to the top of the balloon?
convection
How is most thermal energy in the atmosphere transfered?
From the surface, it would be via convection currents
What is the cycle of a heated fluid that rises and then cools and falls?
It's called the Covection Cycle and it happens with Boiled hot water, soup or whatever, hot air balloons,clouds,and possibly volcanoes.
When a gas is heated is all of the absorbed energy converted to kinetic energy or potential?
When a gas is heated the energy is converted to kinetic energy.
Is the energy input obtained from the energy released by the combustion of a fuel with air in the practical heat engine cycle?
No, the energy which ignites each combustion is supplied by the spark plug.
When heat energy travels by convection energy is transferred by the circulation of heated material?
Yes, when heat travels by convection the energy is transferred by the circulation of a heated fluid, such as air or water.
Why hot sand heats the air not an example of conduction?
I think it is an example on convection.
Will an air conditioner consume energy if main switch is on but air conditioner is in an off cycle?
The equipment might have circuits which remain energised when it is in an off-cycle, but the energy used would probably be less than 1% of the energy used in the on-cycle.
What is heated by the thermal energy wasted by a portable radio?
The air around the radio.
How does the sunlight warm the land air and water?
Land and sea are heated by absorbing radiant energy from the sun. Air is heated indirectly by being in contact (conduction) with land or water.
Why are room heaters kept at the ground level?
To circulate the air. The heaters warm the air closest to them, which rises. This forces cold air to replace the warm air - which is then heated... and the cycle continues.
Heated air molecules in a hot air balloon soon carry thermal energy to the top of the balloon. This is an example of?
Convection.

Convection.
When Heated air molecules in a hot air balloon soon carry thermal energy to the top of the balloon?
convection
What would happen to the water cycle if the sun heated the atmosphere evenly?
If the sun heated the atmosphere evenly, the water vapor in the air wouldn't move from 1 place to another.
What source of energy drives the nitrogen cycle?
The air 78% of the air on earth is made up of nitrogen
What replaces heated air at the equator?
Cool Air! As the heated air rises the heated air starts getting cool. This is because the higher the air is the colder it gets. Then the heated air will be replaced with cold air. As the cold air then comes down near the ground the cool air will become heated because of the sun. Heated Air - Cool Air - Cold Air And On And On It Goes
