“The system” is a large ship and its contents. The inside of the ship and the air outside the ship are at  the same temperature. The ship is sailing north at a constant speed of 20 knots. The engines are powered by burning liquid fuel, and the gaseous by-products (primarily carbon dioxide and water) are vented to the atmosphere, but nothing else enters or leaves the system. Some descriptions of this situation are given below. For each, indicate whether it is true or false, and explain why.

A. The system is at a steady state, because its velocity is constant. However, it is not at equilibriumthe fact that the ship is moving indicates that the forces are not balanced. 

B. The system is not a at steady state, because the amount of fuel inside the system is changing. However, the system is at equilibrium, because i is at the same temperature as the surroundings; there is no driving force for heat transfer.

C. The system is neither at equilibrium nor at steady state.

D. The system is adiabatic, because there is no temperature driving force that would cause heat transfer to occur.

E. The system is an isolated system, because nothing is entering it and there is no heat transfer.
