Thermodynamics - Explaining the Triple Point
Medielab HVL・2 minutes read
The triple point is a state where a substance can exist as a solid, liquid, and gas simultaneously under specific pressure and temperature values, illustrated on a PT diagram through separation lines marking phase transitions. A demonstration of the triple point of water requires a vacuum chamber, pump, and sensors to observe ice, liquid, and vapor coexisting under specific conditions.
Insights
- The triple point is a rare condition where a substance can be solid, liquid, and gas simultaneously, determined by precise pressure and temperature values.
- A pressure-temperature diagram visually represents how a substance transitions between solid, liquid, and gas phases based on pressure and temperature, using distinct lines to mark these shifts.
