Hi there,
Would anyone be able to help with the below problem.
Vertical cylinder, closed at the lower end, fitted with a frictionless piston of mass 200kg and cross-sectional area 0.1m^2. The cylinder contains air which is heated such that its state changes and the piston rises through o.5m. (atmospheric pressure is constant at 100KPa)
Calculate the work transfer to the surroundings if
a) the system is the air in the cylinder only.
b) the system is the air in the cylinder and the piston.
Equations:
None are given but I would think these are relevant:
Force = Pressure x Area
Work = Force x distance
Work = Integral of F dx
Work = integral of P dx
Any help would be appreciated!
