Within an internal combustion engine, the can-shaped component that moves up and down the cylinder and is the main moving part in the engine is the
a. connecting rod.
b. crankshaft.
c. piston.
d. spark plug.

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
