Which of the following items is not a path function?

A. Heat

B. Work

C. Kinetic energy

D. Thermal conductivity

Answer: Option D

Solution(By Examveda Team)

Heat and work are path functions because they depend on how a sysem changes from initial to final state, hence they are state functions.
Thermal conductivity is mainly a function of the motion of the free electrons therefore property of a material, not a path function.

    path func means ditstance travel in differnt direction
    heat,work,K.E,changes based direction of flow
    but thermal conductivity doesnt change same throug out the material
    but heat may vary from point to point in direction of flow
