Engineering Thermodynamics MCQ with Answers

51) Which of the following items is not a path function

Answer is:

thermal conductivity

Explanation:

Heat and work are path functions because they depend on how a system 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.

52) Work done in an adiabatic process between a given pair of end states depends on

Answer is:

the end states only

53) Heat and work are

Answer is:

path functions
