Question

explain work done in vaccum??​

Answer 1

Answer:

• The point is,in a vacuum,there is nothing that the gas can do work on! Also,there is nothing that the gas has to overcome its pressure to expand,so the work it does in expanding is zero. For another thing,pressure of a gas is the force that its particles exert on the walls of their container divided by the area

Answer 2

Answer:

Explanation: therefore the minimum work done is when the external pressure is 0, which is the case under vacuum. This would mean that the work done under vacuum is 0. This is called free expansion. The greater the opposing force then the greater the amount of work done is (as work is equal to force applied over a distance).
