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

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

## Engineering Thermodynamics A manufacturer claims to have a heat engine capable of developing 20 h.p. by receiving heat input of 400 kcal/mt and working between the temperature limits of 227° C and 27° C. His claim is

Cost will be very high
May be possible with lot of sophistications
Not possible
Theoretically possible
