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?

    Increasing the radius of conductor can reduce the resistence, but it also make it difficult to radiate heat. Increasing the number of cores doesn't affect the cooling adoption, just fill the space with coolant.


    For engineering consideration, add cooling support can also increase the maximum capability of the power transmission. When the power requirement increases due to the population increase, technology development, etc., you don't need to rebuild the entire power transmission line, just turn on the air conditioner, what a simple thing! :)


    For the reliability, I don't think it's a big problem, the airconditioner and the fridge can be used more than 5 years without any maintenance. The pain should only exist in the beginning period.
