The interactions between a closed system and its surroundings include energy transfer by heat, boundary work and flow work. a) True b) False

b) False

Explanation:

In close system only energy transfer take place and mass transfer is zero. But on the other hand in open system energy as well mass transfer take place.

Energy transfer means work as well as heat transfer. But we know that in close system there is no any flow of mass so there will not be any flow work, only boundary work will associated with close system. But in open system flow work take place.
