41. Zeroth law of thermodynamics-
Deals with conversion of mass and energy
Deals with reversibility and irreversibility of process
States that if two systems are both in equilibrium with a third system, they are in thermal equilibrium with each other
Deals with heat engines
43. The term "Efficiency" in a thermodynamic Cycle is a consequence of-
First law of thermodynamics
Second law of thermodynamics
Third law of thermodynamics
Zeroth law of thermodynamics
46. Intensive property of a system is one whose value-
Depends on the mass of the system, like volume
Does not depend on the mass of the system, like temperature, pressure etc.
Is not dependent on the path followed but on the state
Is dependent on the path followed and not on the state
50. When two bodies are in thermal equilibrium with a third body, they are also in thermal equilibrium with each other. This statement is called-
Zeroth law of thermodynamics
First law of thermodynamics
Second law of thermodynamics
