In adiabatic process heat is neither added nor removed from the system. So the work done by the system (expansion) in adiabatic process will result in decrease of internal energy of that system (From I st law). As internal energy is directly proportional to the change in temperature there will be temperature drop in an adiabatic process.
Processes that release energy are defined as exothermic. Processes that absorb energy are termed endothermic.

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.
Why carnot cycle is called a two adiabatic and two isothermal process?
The Carnot cycle consists of two adiabatic processes, where there is no heat transfer, and two isothermal processes, where temperature remains constant. The adiabatic processes involve compression or expansion of the gas without heat exchange, while the isothermal processes occur at constant temperature with heat exchange. This combination allows the Carnot cycle to achieve maximum efficiency in a heat engine.
What is the rate of adiabatic temperature change in saturated air?
The rate of adiabatic temperature change in saturated air is approximately 0.55°C per 100 meters of elevation gain, known as the dry adiabatic lapse rate. If the air is saturated and undergoing adiabatic cooling, the rate is around 0.5°C per 100 meters, referred to as the saturated adiabatic lapse rate.
How does air temperature affect the dew point?
Temperature (dry adiabatic lapse rate) changes at about 2 per degree F per 1000 ft, dew point more slowly (saturated adiabatic lapse rate), at about 3 degree F per 1000 ft. See http://en.wikipedia.org/wiki/Adiabatic_lapse_rate. jb
Explain the Difference between adiabatic and isothermal compression?
"Adiabatic process" refers to processes that take place in a closed system with no heat interaction with it's surroundings. "Isentropic process" refers to processes that take place in a closed system with no heat interaction with the surroundings (adiabatic process) and internally reversible. This is, no internal generation of entropy, entropy stays constant, which is what is meant by "isentropic". We can also say, an isentropic process is one where entropy stays constant, and no heat interaction of the system with the surroundings takes place (adiabatic process). Or, an adiabatic process can be irreversible, or reversible (isentropic).
What are temperature changes that occur even though heat is not added or subtracted?
Temperature changes may occur due to changes in pressure, volume, or physical state of a substance, known as adiabatic processes. This is governed by the ideal gas law, which relates pressure, volume, and temperature of a gas. Additionally, temperature changes can result from chemical reactions or phase changes within a system.
What name is given to the processes whereby the temperature of the air changes without the addition or subtraction of heat?
Adiabatic processes.
What is the name for temperature changes which involves no heat transfer?
Adiabatic
Temperature changes are those which do not involve the addition or subtraction of heat?
Adiabatic
Changes in temperature that result solely from the expansion or compression of air are called?
adiabatic
Changes in temperature that result from the cooling of rising air or the warming of sinking air are?
Adiabatic
What is the name for temperature changes that involve no heat transfer?
Adiabatic processes involve temperature changes that do not involve heat transfer. This means any increase or decrease in temperature is due to internal energy changes within the system, rather than heat being added or removed from the surroundings.
What does the word adiabatic mean?
Adiabatic refers to a process in thermodynamics where there is no heat exchange with the surroundings. This means that the change in internal energy of the system is solely due to work being done on or by the system. Adiabatic processes are often rapid and can result in changes in temperature or pressure.
What is an adiabatic process?
An adiabatic process is one in which there is no heat transfer into or out of the system. This means that any change in internal energy of the system is solely due to work done on or by the system. Adiabatic processes are often rapid and can lead to changes in temperature and pressure without heat exchange.
Definition of adiabatic cooling?
Adiabatic cooling is the process by which the temperature of a mass of air decreases as it rises in the atmosphere and expands due to a decrease in pressure. This cooling occurs without any heat exchange with the surrounding environment.
What is different between adiabatic system and isothermal system?
An adiabatic system does not exchange heat with its environment, whereas an isothermal system maintains a constant temperature during a process by exchanging heat with its surroundings. Therefore, in an adiabatic process, the internal energy of the system changes without heat transfer, while in an isothermal process, the temperature remains constant.
What is steam temperature after adiabatic expansion?
The steam temperature after adiabatic expansion depends on the specific conditions of the expansion process, such as initial temperature, pressure, and volume. During adiabatic expansion, the internal energy of the steam decreases, causing its temperature to drop. The final temperature can be determined using the appropriate thermodynamic equations.
