## Engineering Thermodynamics Intensive property of a system is one whose value

Is dependent on the path followed and not on the state
Is not dependent on the path followed but on the state
Depends on the mass of the system, like volume
Does not depend on the mass of the system, like temperature, pressure, etc.

## Engineering Thermodynamics According to Kelvin-Planck’s statement of second law of thermodynamics,

It is impossible to construct a device which operates in a cyclic process and produces no effect other than the transfer of heat from a cold body to a hot body
It is possible to construct an engine working on a cyclic process, whose sole purpose is to convert heat energy into work
It is impossible to construct an engine working on a cyclic process, whose sole purpose is to convert heat energy into work
None of these

## Engineering Thermodynamics Which of the following is the correct statement?

All engines are designed as reversible in order to obtain maximum efficiency.
All the reversible engines have the same efficiency.
All the reversible and irreversible engines have the same efficiency.
Irreversible engines have maximum efficiency.

## Engineering Thermodynamics Kelvin Planck's law deals with
