Exercises to the text "Thermodynamics"
1. Answer the questions to the text:
- What is thermodynamics?
- Where can thermodynamics be applied?
- How can physical life be described?
- Are transformations perfectly efficient?
- Can the work output of a system be greater than the net energy input?
- Is it possible to create a perpetual motion machine?
- What creations were made due to the laws of thermodynamics?
- How can any physical system be described?
- What do the laws of thermodynamics predict?
2. Insert a preposition or a conjunction if necessary :
- These transformations are never perfectly efficient, … the second law of thermodynamics shows.
- Thermodynamics is the study of the relationships … heat, work, and energy.
- The work output of a system can never be greater … the net energy input.
- The three laws of thermodynamics describe these changes and predict the equilibrium state … the system.
- The laws of thermodynamics made possible such highly useful creations … the internal combustion engine and the refrigerator.
- It has a clear application … chemistry, biology, and other sciences.
- It can be described … specifying its properties, such as pressure, temperature, or chemical composition.
- Any physical system will spontaneously approach … an equilibrium.
