Question 14 (1 point) For a system that contains a rock falling through the air, which situation is always true?

The total mechanical energy of the system is conserved.

The total energy of the system is conserved.

The total potential energy of the system is conserved.

The total kinetic energy of the system is conserved.

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.

Complete the sentence to describe the law of conservation of energy. the law of conservation of energy states that energy cannot be created
