Compression Work

Postby Eric Quach 1C » Sun Feb 03, 2019 7:05 pm

If a piston is compressing then is work being done to the system or is the system doing work on the surrounding? What does this mean for negative and positive values of work?

If a piston is compressing, then work is being done to the system and the value of work would be positive.

Work is being done on they system by compressing it. Following the equation work= Pressure*area*distance, it will give you a positive value.

If the piston is being pushed up by the gas that means that the gas is performing work on the piston which results in positive work and if the piston being down that means that the piston is performing work onto the gas meaning that work relative to the gas is negative.
