Relative temperatures during freezing of Water

Click For Summary
SUMMARY

When 100ml of water is placed in a freezer, it initially cools to 0ºC, where it remains for a period due to the release of latent heat during the phase transition from liquid to solid. This constant temperature phase occurs as the water undergoes freezing, which requires energy removal without a temperature change. Once the latent heat is fully released, the temperature of the water continues to decrease below 0ºC.

PREREQUISITES
  • Understanding of latent heat and phase changes
  • Basic knowledge of thermodynamics
  • Familiarity with temperature measurement
  • Concept of freezing point of water
NEXT STEPS
  • Research the concept of latent heat in phase transitions
  • Study the thermodynamic principles of freezing and melting
  • Explore temperature measurement techniques in phase change experiments
  • Investigate the effects of pressure on the freezing point of water
USEFUL FOR

Students in physics or chemistry, educators teaching thermodynamics, and anyone interested in the physical properties of water during freezing processes.

Hi I was wondering if anyone could help me out with this question?

You place 100ml of water into a freezer and monitor the variation of the temperature of the water with time.
After some time you find that the temperature reaches 0ºC, then remains constant at 0ºC for a period of time before continuing to fall.

What happens to the water during the period in which the temperature is constant?

Thnx,

Josh

At 0 degree C, water has to loose its latent heat for the phase transformation, that is why temperature remains constant for some time at 0 deg. C.
