Vedclass · Answer

(D) state function is a property whose value depends only on the current state of the system and not on the path taken to reach that state.$(i)$ The height of a hill is a fixed property of the location,independent of the path taken to reach the top,so it is a state function.$(ii)$ The distance covered depends on the path taken,so it is a path function.$(iii)$ The change in energy (internal energy) is a state function because it depends only on the initial and final states of the system.Therefore,both $(i)$ and $(iii)$ are state functions.

Which of the following is a state function: $(i)$ height of a hill,$(ii)$ distance covered in climbing the hill,$(iii)$ change in energy while climbing the hill?
