HKIE Professional Assessment - Energy Discipline Practice Questions - HKIE Professional Assessment - Energy Discipline (Hong Kong Institution Of Engineers) Exam

The total rate of heat added to the system minus the net rate of work done by the system equals the net rate of energy outflow carried by fluid mass streams. The total entropy of an isolated thermal system must always increase over time during any irreversible energy transformation. Heat cannot spontaneously flow from a lower temperature body to a higher temperature body without external mechanical work input. The absolute zero temperature is reached when all molecular thermal kinetic energy ceases.
