Study Notes
Third Law of Thermodynamics
- Entropy approaches a constant value as temperature nears absolute zero.
Absolute Zero
- Defined as 0 Kelvin, it represents the theoretical temperature where all molecular motion ceases.
Entropy
- A thermodynamic quantity indicating energy within a system that cannot perform mechanical work.
Kelvin
- A unit of measurement for absolute temperature, represented by the symbol K; previously referred to as degree Kelvin.
System
- Comprises interrelated components that operate collectively to achieve a specific purpose.
Constant Value
- Refers to a fixed numerical entry within a cell of a worksheet, maintaining the same value unless altered.
Specific Heat
- The quantity of heat needed to increase the temperature of one gram of a substance by 1 degree Celsius, demonstrating heat capacity.
