How Does Deposition Affect State Change and Heat Release?

Click For Summary
SUMMARY

The discussion centers on the state change graph of matter undergoing deposition, specifically addressing the transition from gaseous to solid states. Participants clarify that the heat release during deposition can be represented in a temperature vs. time plot, emphasizing the importance of thermogravimetric analysis. The conversation also touches on the misconception regarding the boiling point of water, highlighting the temperature range for boiling as 90 to 110°C under varying conditions.

PREREQUISITES
  • Understanding of phase changes in matter, specifically deposition.
  • Familiarity with temperature vs. time plots in thermodynamics.
  • Knowledge of thermogravimetric analysis techniques.
  • Basic principles of heat transfer during phase transitions.
NEXT STEPS
  • Research the principles of deposition and its graphical representation.
  • Learn about thermogravimetric analysis and its applications in material science.
  • Study the heat transfer mechanisms during phase changes, focusing on deposition.
  • Investigate the factors affecting the boiling point of water and other substances.
USEFUL FOR

Students studying thermodynamics, educators teaching phase changes, and researchers interested in material properties and heat transfer processes.

Homework Statement



How would the state change graph of some matter undergoing deposition look like?

2. The attempt at a solution

I would assume that since it is undergoing deposition, it would just be a slope from the gaseous state to the liquid state. However I am not sure of this? How would one then calculate the heat released during this process, is it at all possible?

You mean temperature vs time plot?
 
Yes. Precisely a heat added vs. temp plot.
 
Ok. So this is an example of a heat added vs. temp diagram of a sublimation phase change from my workbook.

They ask to choose the one on the left(a) or right (b).

I think it is (b) because during the phase change, the temp would continually rise, no?

So you mean water boils between - say - 90 and 110°C? I was always taught water boils at 100.
