What type of heat energy occurs when warm air rises and cool air falls?

Are you asking about heat transfer or latent heat? As warm air rises, decreasing air pressure will allow moisture present to cool and condense. Once condensation occurs, latent heat , or the energy hidden within water molecules, is released. This is an example of adiabatic cooling, by air pressure change alone. As that same parcel of air falls, air pressure will compress the air (adiabatically) and warm it. As the falling air warms, its ability to hold moisture increases.

When does convection occurs?
When a warm fluid rises and a cool fluid sinks.
Do convection currents happen when cool air rises?
No. Convection occurs when warm air rises and cool air sinks. It is not limited to air, either, but can occur in virtually any liquid or gas.
Does cool air sink while warm air rises?
yes the cool denser air sink while the warm less dense rises
Which statement regarding air temperature is NOT trueCool air rises and warm air falls.Air heats up more quickly than land.Warm air is less dense than cool air.Air heats up more quickly than water?
"Cool air rises and warm air falls" is false. Cool air is denser than warm air, and therefore warm air will rise above cold air.
Is condensation a process in the hydrological cycle?
For animals it is. The function of sweating, for instance, is to produce evaporation of water in such a way as to cool this skin. Evaporation of water from the ocean, also, occurs when the ocean is warm and the air is cool.
When air rises does it cool down?
Yes. (As the density falls, it expands.)
When does convection occurs?
When a warm fluid rises and a cool fluid sinks.
Do convection currents happen when cool air rises?
No. Convection occurs when warm air rises and cool air sinks. It is not limited to air, either, but can occur in virtually any liquid or gas.
When air rises does it expand and cool adiabatically?
Yes. Adiabatic cooling occurs when there is a change in only pressure.
How does convection happen?
Liquids and gasses tend to expand when heated, this lowers the density, thus warm "air" rises and cool air falls.
Why is the attic always warmer than the basement?
because the attic is at the top of the house where warm air rises and the asement is at the bottom where cool are falls!
What energy transformations take place when you an electric fan to cool a room?
The energy transformation that occurs is electrical to mechanical
Why making air rise makes it cool?
When it rises, it gets into an area of less pressure, therefore it will expand. Since this takes energy away from the air, it will cool.
Why do we use warm air in a hot air balloons?
This is because of convection. Hot air rises and cool air falls which causes the balloon to rise.
Is a hot air balloon an example of convection?
Yes, It is because in a hot air balloon the hot air rises and the cool air falls down.

Does water vapor cool or heat as it rises?
cool
