Study Notes
Thermodynamics Basics
- The word 'thermodynamics' literally means "heat power" or "heat movement".
- 1 BTU (British Thermal Unit) is equivalent to 1.055056 kilojoules.
- Thermodynamics applies to the relationships between heat, work, and energy.
Laws of Thermodynamics
- The first law of thermodynamics is also known as the Law of Energy Conservation.
- The first law of thermodynamics states that energy cannot be created or destroyed, only converted from one form to another.
Units and Conversions
- The SI unit for force is not mentioned in the text, but it is actually the Newton (N).
- 1 English ton is equivalent to 907.18474 kilograms.
Thermodynamic Cycles
- Thermodynamic cycles govern the operation of heat engines, refrigerators, and other devices that convert thermal energy into mechanical energy or vice versa.
