Question
which of the following items is not a path function
which of the following items is not a path function
Open in App
Solution
The correct options are
B kinetic energy
C thermal conductivity
Path functions are those quantities which depend on the transition of a system from initial to final state.Heat and work are path functions because they depend on how a sysem changes from initial to final state, hence they are state functions. Kinetic energy is the work done on a body to give it motion, hence it is also a state function, not a path function.Thermal conductivity is mainly a function of the motion of the free electrons therefore property of a material, not a path function.
