SUMMARY

The discussion centers on the temperature required for supercooled water to freeze completely solid. It is established that supercooled water must be below 0 degrees Celsius to transition into ice, as the freezing process releases heat. The conversation explores the energy balance between warming supercooled water and the energy released during the freezing of water at 0 degrees Celsius. The specific heat capacities of ice and water are also highlighted as critical factors in this energy exchange.

PREREQUISITES
  • Understanding of supercooled water and its properties
  • Knowledge of phase changes and heat transfer
  • Familiarity with specific heat capacity concepts
  • Basic thermodynamics principles
NEXT STEPS
  • Research the specific heat capacities of water and ice
  • Study the thermodynamic principles of phase transitions
  • Explore the concept of supercooling in liquids
  • Learn about energy balance equations in thermodynamics
USEFUL FOR

Students and professionals in physics, chemistry, and engineering fields, particularly those interested in thermodynamics and phase transitions.

Im having a discusion reguarding what temperature (celsius) supercooled water needs to be if it was to freeze completely solid. Going from liquid to solid "produces" heat. Therefor it is obvious that the temperature needs to be somewhat below zero.

What temperature (celsius) is needed if all the supercooled water should turn into ice and stay at zero degrees afterwards?

Thanks!

The energy to warm M grams of supercooled water from minus X degrees C to 0 degrees C equals the energy given off when M grams of water at 0 degrees C turns into ice at 0 degrees C?
 
Maybe it is more helpful to start with M grams of ice at 0 degrees C and then add energy E to turn the ice into M grams of water at 0 degrees C and then remove the same energy E from the water to bring it down to minus X degrees C?

Mmmmm... I'd have thought that it would be the energy required to warm M gram of ice from minus X degrees C to 0 degrees C that has to balance the energy given off by the water turning to ice. The specific heat of ice is appreciably less than that of water.

I think I had that backwards, yes?
