ethical dilemmas are rarely crystal clear and there are often more than one point of view to any given situation. How would you handle a co-worker behaving in an unethical manner? Would your response change if you knew it was an isolated event?

Question 2 1 pts What defines a closed (or isolated) system? Choose ALL correct responses. It contains only one object. The net force on the system is zero. The momentum of the system is conserved. There is no friction involved Motion only occurs in one direction.

We consider two phases of solid carbon: diamond and graphite, with S0diamond= 2.44 J/(K ∙ mol) and S0 graphite = 2.3 ∙ S0diamond . Which of the two carbon modifications is more stable if we establish a thermal equilibrium between them in an isolated system?
