What is an example of an adiabatic process?

An example of an adiabatic process is the vertical flow of air in the atmosphere; air expands and cools as it rises, and contracts and grows warmer as it descends. Another example is when an interstellar gas cloud expands or contracts. Adiabatic changes are usually accompanied by changes in temperature.

What happens to pressure in adiabatic expansion?

As a result of the adiabatic expansion the pressure of the gas is reduced to 1 atm. (a) Find the volume and temperature of the final state. (b) Find the temperature of the gas in the initial state. (c) Find the work done by the gas in the process.

How is adiabatic expansion calculated?

Thus for a reversible adiabatic process and an ideal gas, CVdT = −PdV. (The minus sign shows that as V increases, T decreases, as expected.) But for a mole of an ideal gas, PV = RT = (CP − CV)T, or P = (CP − CV)T/V.

What does adiabatic expansion mean?

Expansion in which no heat is added to or subtracted from the air, which cools during the expansion because of the work done by the air. Ref: Lewis. Prev: adiabatic efficiencyNext: adiabatic temperature Glossary Search.

How do you know if something is adiabatic?

An adiabatic process is one in which no heat is gained or lost by the system. The first law of thermodynamics with Q=0 shows that all the change in internal energy is in the form of work done.
