Study Notes
SI Unit of Temperature
- The SI unit of temperature is Kelvin.
Enthalpy Definition
- Enthalpy is the heat required to cause a complete conversion between two phases at a constant temperature.
System Classification
- An open system is one in which there might be an exchange in energy but not mass.
- A closed system is one in which there might be an exchange in energy and mass.
- An isolated system is one in which there is no exchange in energy or mass.
Refrigerator Coil
- The coil on the back of most refrigerators is called the condenser.
NTP Meaning
- NTP stands for Normal Temperature and Pressure.
Gas Laws
- Avogadro's hypothesis states that molecular weights of all gases occupy the same volume.
Substance Classification
- A sub-cooled liquid is a substance whose temperature is less than its saturation temperature.
- A saturated vapor is a substance whose temperature is equal to its saturation temperature.
- A superheated vapor is a substance whose temperature is greater than its saturation temperature.
Thermodynamics Scope
- Thermodynamics is a science that includes the study of energy storage, energy transfer, and energy utilization, but not energy transformation.
