Question on thermodynamics

Former Community Member
Former Community Member
Hello everyone, I have a question on the energy cost of compressing gas.

I didn't find a community about thermodynamics, so I post the question here..


When gas absorbs heat. its volume increases from v1 to v2. When we compress the volume of the same gas from v2 to v1, does the energy required equal to the heat it absorbs? Does the temperature affect the energy required?

    Reliability is a big problem: If your fridge breaks down you lose some food and it's annoying. If the airconditioner breaks down the room gets hot (or cold), you get a bit uncomfortable and it's annoying.  If the cooling on a transmission circuit breaksdown you could black-out a city - I think that that is a little more serious than annoying.


    As I said before, cooling of transmission cables is not a new concept; there is a limit to what can be done, take a look at the literature out there.
