Sample interview questions: Describe the laws of thermodynamics and their applications.
Sample answer:
The Laws of Thermodynamics:
- The Zeroth Law of Thermodynamics:
- If two systems are in thermal equilibrium with a third system, they are in thermal equilibrium with each other.
-
Application: This law provides the basis for temperature measurement and the development of thermometers.
-
The First Law of Thermodynamics:
- Energy cannot be created or destroyed, only transferred or transformed from one form to another.
-
Application: This law is fundamental to the design and operation of heat engines, refrigerators, and other thermodynamic systems.
-
The Second Law of Thermodynamics:
- The entropy of an isolated system always increases over time.
-
Application: This law has profound implications for the direction of spontaneous processes, the efficiency of heat engines, and the arrow of time.
-
The Third Law of Thermodynamics:
- The entropy of a perfect crystal at absolute zero is zero.
- Application: This law is used to det… Read full answer
