Objective 07: Polytropic Expansion and Compression

Question 1

Are most expansion and compression processes either isothermal or adiabatic?

Answer 1

No

Question 2

Polytropic Process

Answer 2

Where there is variation in pressure, volume, and heat flow

Question 3

How does the calculation of work performed in a polytropic expansion/compression differ from an adiabatic process?

Answer 3

n is used instead of γ

Question 4

Order the magnitude of work performed for the same expansion in terms of conditions from largest to smallest.

Answer 4

1. Isobaric
2. Isothermal
3. Polytropic
4. Adiabatic

Question 5

Order the magnitude of work performed for the same compression in terms of conditions from largest to smallest.

Answer 5

1. Adiabatic
2. Polytropic
3. Isothermal
4. Isobaric
