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.
