Adiabatic processes

• 55-20 group student Rahmonov Avazbek

An adiabatic process is a process during which there is no transfer of heat from or to the system. ... Heat transfer to and from the system is prevented by either perfectly insulating the system from its environment or by carrying out the change rapidly so that there is no time for any exchange of heat.

Adiabatic Compression and ExpansionAdiabatic CompressionPressure ( P) > Volume (V)T, E, and U increase during compression.In cylinders of a car, the compression of the gas-air mixture takes place in no time that there could be an exchange of heat between them.

Adiabatic Expansion The work is done by the gas in expanding the volume and there's a decrease in the temperature.

Adiabatic processes

• 1st law of thermodynamics in the form (imperfect form)
• is a statement of the Conservation of energy (heat in = heat out)!

Adiabatic processes

• Left hand side (represents?):
• Diabatic heating, which includes Latent Heat Release, Sensible Heating, and Radiational Heating.

• Right hand side:
• Term 1: Internal Energy (due to Temperature)
• Term 2: “pressure work” term or work done by pressure by the environment on a parcel.
• (expansion – heat added to system diabatically
• contraction - heat removed diabatically)
