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.
What else can I help you with?
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.
What Type energy transfer occurs when hot water flows through cool water?
Convection. As the hot water flows through the cool water, it transfers thermal energy through the bulk movement of the fluid. The hotter water rises and the cooler water sinks, creating a circulating flow that redistributes the thermal energy throughout the system.
As moist air rises its temperature will what?
The air temperature rises when particles in the air begin to move faster. The energy of the motion of particles is called thermal energy.
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 type of thermal energy accounts for the movements of clouds?
The thermal energy that accounts for the movement of clouds is called convection. This occurs when warm air rises due to being less dense than the surrounding cool air, creating vertical air currents that carry clouds along with them.
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.
What energy transformations take place when you an electric fan to cool a room?
The energy transformation that occurs is electrical to mechanical
When cool air cools what happens?
It gets colder. And the energy increases so the particles move further apart.
The process causes rising air to cool?
Expanding air cools. Work has to be done on the molecules for them to spread apart. A positive amount of work means the kinetic energy in the system decreases. As the air rises, the pressure decreases, causing the molecules to loose energy, which is what we perceive as the cooling of the air.
