Chapter 10, Problem 18A

Interpretation Introduction

Interpretation: The reason due to which engineers define energy and work differently from chemist is to be stated.

Concept introduction: The movement of an object from one place to other by applying force is termed as work. The measurement of the capacity to do work is termed as energy. The measurement of work and energy is done in joule.

Answer to Problem 18A

The chemists synthesize and analyze the molecules themselves whereas engineers create models and machines that can operate and generate energy.

Explanation of Solution

According to chemist’s point of view, work and energy as what is being performed or analyzed on the system. According to the engineer’s point of view, work and energy as what machine puts out to the surroundings by the system. The reason behind it is theirs purpose. The chemists synthesize and analyze the molecules themselves whereas engineers create models and machines that can operate and generate energy.

Conclusion

Thus, chemists synthesize and analyze the molecules themselves whereas engineers create models and machines that can operate and generate energy.
