Homework Answers
1.
a)
Diagram 1 cannot represent a real physical process. Here, the energy of the stuff and surroundings, both are increasing which will not be possible from the conservation of energy.
b)
The second diagram represent the real physical process in which the stuff is absorbing energy from the surroundings.
Examples are: Air Conditioner and Refrigerator

Recruiting and selection are interdependent, two-way processes in which both employees and recruits try to look appealing to the other while learning as much as they can about their potential fit. Impression management is the process through which people and employers try to control the impressions others have of them. How do applicants and employers try to look appealing to each other during the staffing process?

Diagram 1 Diagram 2 The diagrams above use arrows to represent the speed of a gas particle. Which of the diagrams best represents the speed of the particles of a gas at a fixed temperature, and why? A) Diagram 1, because all the particles have the same speed Diagram 1, because the particles are moving in different directions Diagram 2, because the particles have a net kinetic energy of zero. D) Dipam 2 because the particles have a variety of...
