CHAPTER 1: INTRODUCTION TO

THERMODYNAMICS AND ENERGY

END OF CHAPTER PROBLEM SOLUTIONS

1.1) F or the following systems, determine whether the system described is best modeled

as an isolated, closed, or open system:

(a)steam flowing through a turbine (b)an incandescent light bulb (c)a fuel pump in a moving automobile (d)an anchor of a sunken ship resting 3000 m below the surface of the ocean (e)the roof of a house

Solution:

(a)Open System (b)Closed System (c)Open System (d)Isolated System – could be modeled as a closed system if something is being done to it.(e)Closed System 1.2) F or the following systems, determine whether the system described is best modeled

as an isolated, closed, or open system:

(a) a tree growing in a forest (b)a television (c)a laptop computer (d)the Voyager 2 spacecraft in its current state (e) the Messenger spacecraft as it moved into orbit around Mercury

Solution:

(a)Open System (b)Closed System (c)Open System (considering the cooling air passing through the system) (d)Isolated System (e)Open System (would have been expelling mass with a rocket burn) 3 / 4

1.3) For the following systems, determine whether the system described is best modeled

as an isolated, closed, or open system:

(a) an inflated tire (b) a lawn sprinkler actively in use (c) a cup filled with liquid water (d) an engine’s radiator (e) a rock formation 200 m below the surface of the earth

Solution:

(a) Closed System (b) Open System (c) Closed System, unless significant evaporation is actively occurring (which would make it an open system) (d) Open System (e) Isolated System

1.4) For the following systems, determine whether the system described is best modeled

as an isolated, closed, or open system:

(a) a pump supplying water to a building (b) a tea kettle containing boiling water (c) an active volcano (d) a solid gold bar placed inside a very well-insulated box (e) a chair

Solution:

(a) Open System (b) Open System (c) Open System (d) Isolated System (e) Closed System

1.5) For the following systems, determine whether the system described is best modeled

as an isolated, closed, or open system:

(a) a pulley on an elevator (b) a bathtub (c) a human being (d) a piece of metal being shaped on a lathe (e) a comet orbiting the Sun in the Oort cloud (the cloud of inactive comets located well beyond the orbits of the planets)

Solution:

(a) Closed System (b) Open System if being filled or emptied. If it is just sitting as an empty bathtub, it is a closed system.
