Why do I get negative work done for adiabatic compression of air?

WebIf, for example, the system is compressed, then the work is done on the system by the surrounding so the work is positive and the internal energy of the system increases. Conversely, if the system expands (i.e., system surrounding expansion, so free expansions not the case), then the work is negative as the system does work on the surroundings ... WebAs for the sign, if the cycle is clockwise, that means the higher line (higher work area) was L to R (positive work), so the total W is positive. if the cycle is counterclockwise, that means the higher line (higher W area) was R to L (negative work), so the total W is negative (work was done ON the gas). WebWhen we multiply a function by a positive constant, we get a function whose graph is stretched or compressed vertically in relation to the graph of the original function. If the constant is greater than 1, we get a vertical stretch; if the constant is between 0 and 1, we get a vertical compression. The graph below shows a function multiplied by ... establishing organizational goals

WebThe force exerted back by the spring is known as Hooke's law. \vec F_s= -k \vec x F s = −kx. Where F_s F s is the force exerted by the spring, x x is the displacement relative to the unstretched length of the spring, and k k is the spring constant. The spring force is called a restoring force because the force exerted by the spring is always ...

Pros and Cons of a Compressed Work Schedule

WebThus, since the internal energy change is positive the work done is negative. The relation can also be corroborated by the fact that, during adiabatic compression as the internal energy rises, the work is done by the surrounding on the system and hence work done by system on surrounding is negative. http://mccord.cm.utexas.edu/courses/fall2016/ch301/thermo-select-problems.pdf
