An adiabatic process occurs without transferring heat or mass between a thermodynamic system and its surroundings. Unlike an isotherm process, an adiabatic process transfers energy to the surroundings only as work. It also conceptually under girds the theory used to expound the first law of thermodynamics and is therefore a key thermodynamic concept.
Some chemical and physical processes occur too rapidly for energy to enter or leave the system as heat, allowing a convenient "adiabatic approximation". For example, the adiabatic flame temperature uses this approximation to calculate the upper limit of flame temperature by assuming combustion loses no heat to its surroundings.
In meteorology and oceanography, adiabatic cooling produces condensation of moisture or salinity, over saturating the parcel. Therefore, the excess must be removed. There, the process becomes a pseudo-adiabatic process whereby the liquid water or salt that condenses is assumed to be removed upon formation by idealized instantaneous precipitation. The pseudo adiabatic process is only defined for expansion because a compressed parcel becomes warmer and remains under saturated.

A change in temperature without an accompanying change in the amount of heat present is called what?
It is called adiabatic or an adiabatic process.
What is the rate of cooling as you increase in elevation?
The rate at which adiabatic cooling occurs with increasing altitude for wet air (air containing clouds or other visible forms of moisture) is called the wet adiabatic lapse rate, the moist adiabatic lapse rate, or the saturated adiabatic lapse rate.
Why carnot cycle is called a two adiabatic and two isothermal process?
Adiabatic means there's no heat transference during the process; Isothermal means the process occurs at constant temperature. The compression and expansion processes are adiabatic, whereas the heat transfer from the hot reservoir and to the cold reservoir are isothermal. Those are the two adiabatic and isothermal processes.
What is the rate of adiabatic temperature change in saturated air?
As I recall from flight school, the adiabatic lapse rate is 4.5oF per 1000 feet.
What are everyday examples of adiabatic process?
Air is made up of a mixture of gases that is subject to adiabatic heating when it is compressed and adiabatic cooling when it is expanded.
Adiabatic processes cause cooling by?
Adiabatic cools by decompression.
Is melting process is adiabatic process?
An adiabatic process in the opposite of a diabatic process. The adiabatic process occurs without the exchange of heat with its environment. A diabatic process exchanges heat with the environment.
What is an adiabatic process?
An adiabatic process is a thermodynamic process, there is no gain or loss of heat.
What is adiabatic wall?
An adiabatic wall can be defined as a wall through which no energy transfer takes place.
Why is saturated adiabatic lapse rate a lesser than dry adiabatic lapse rate?
When environmental lapse rate is more than dry adiabatic lapse rate, the atmosphere is said to be in
Is it possible to have entropy generation in a reversible adiabatic system?
No, a reversible adiabatic system is also known as isentropic.
What is adiabatic proccess?
An adiabatic process is a process that takes place without any loss or gain of heat.
What is adiabatic cooling?
Adiabatic cooling is cooling that occurs without removing any energy from the system. It often occurs when a gas is decompressed. Adiabatic heating and cooling play an important role in weather.
A change in temperature without an accompanying change in the amount of heat present is called what?
It is called adiabatic or an adiabatic process.
What does a sudden burst of cycle tire represent the opsions are 1.isothermal 2.isobaric 3.adiabatic?
adiabatic
What is adiabatic and diathermal wall?
the temperature that is within the system closed by adiabatic wall is called adiabatic wall temperature
What is the rate of cooling as you increase in elevation?
The rate at which adiabatic cooling occurs with increasing altitude for wet air (air containing clouds or other visible forms of moisture) is called the wet adiabatic lapse rate, the moist adiabatic lapse rate, or the saturated adiabatic lapse rate.
