Non-adiabatic dynamics refers to a type of molecular or atomic motion in which the energy levels of the relevant electronic states change quickly relative to the nuclear motion. This leads to a breakdown of the Born-Oppenheimer approximation, where the motion of electrons and nuclei are treated separately. In non-adiabatic dynamics, the motion of both electrons and nuclei must be considered simultaneously, making it a more complex and computationally challenging problem.

What is the difference between isolated system and non flow adiabatic system?

An isolated system is a system that doesn't not interact with its surroundings. No interactions at all. No work, no heat transfer. An adiabatic system is one that does not permit heat transfer between the system and its surroundings. It can do work on the surroundings.


What is the significance of the adiabatic gradient in the study of atmospheric science?

The adiabatic gradient is important in atmospheric science because it helps us understand how temperature changes with altitude in the atmosphere. This gradient helps explain the behavior of air parcels as they rise or sink, which is crucial for predicting weather patterns and understanding atmospheric dynamics.

How does entropy change in an adiabatic process?

In an adiabatic process, entropy remains constant.


What is the difference between adiabatic and isentropic processes in thermodynamics?

In thermodynamics, adiabatic processes do not involve heat transfer, while isentropic processes are reversible and adiabatic.


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 adiabatic wall?

An adiabatic wall can be defined as a wall through which no energy transfer takes place.


How does enthalpy change during adiabatic expansion?

During adiabatic expansion, enthalpy remains constant.


Is it possible to have entropy generation in a reversible adiabatic system?

No, a reversible adiabatic system is also known as isentropic.


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.
