Aside from there being no heat transfer, is there any other important characteristic we should know about adiabatic systems?

### Re: Adiabatic system

I think adiabatic just means that there is no heat flow (insulated) therefore q = 0 and the change in internal energy (delta u) = w

### Re: Adiabatic system

An adiabatic system is also an insulated system where there is no heat flow, so q=0.

### Re: Adiabatic system

Adiabatic systems are isolated systems, in which both energy/heat and matter are not transferred to the surroundings. Therefore q=0 and delta U=w (using the equation delta U = q + w)

adiabatic process is one that occurs without transfer of heat or matter between a thermodynamic system and its surroundings. In an adiabatic process, energy is transferred to its surroundings only as work.

### Re: Adiabatic system

I believe adiabatic systems can also occur in closed systems, since even if no heat is being transferred, work can still be transferred as energy, making it a closed system.

### Re: Adiabatic system

Adding on to the post above, pg. 268 of the textbook says that in an adiabatic system, the change in internal energy is equal to the work done.

### Re: Adiabatic system

An example of adiabatic system could be when change in temperature = 0, no heat flow(q=0), but work is being done, like in an insulated container with the gas filled in it expanding.
