Reversible process (thermodynamics): Quiz

Question 1: Reversible processes define the boundaries of how efficient heat engines can be in thermodynamics and engineering: a reversible process is one where no heat is lost from the system as "waste", and the machine is thus as efficient as it can possibly be (see ________).
Thermodynamic cycleCarnot cycleStirling cycleHot air engine

Question 2: During a demonstration of the ________, the disks revolved and machinery fastened to the shaft was operated by the engine.
Boundary layerEnthalpyPumpTesla turbine

Question 3: [1] For example, an infinitesimal compression of a gas in a cylinder where there exists ________ between the piston and the cylinder is a quasistatic, but not reversible process.
ForceFrictionDrag (physics)Lift (force)

Question 4: It was developed during Tesla's research in ________ where the current's magnitude and direction varied cyclically.

Question 5: If the turbine's operation was reversed, the disks acted as a ________.

Question 6: In thermodynamics, a reversible process, or reversible cycle if the process is cyclic, is a process that can be "reversed" by means of ________ changes in some property of the system without loss or dissipation of energy.

Question 7: A reversible process changes the state of a system in such a way that the net change in the combined ________ of the system and its surroundings is zero.
