How Does Deposition Affect State Change and Heat Release?

[Speedking96]

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?

 

[Speedking96]

Yes. Precisely a heat added vs. temp plot.

 

[Speedking96]

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?

 

[Borek]

Google for thermogravimetric curves/analysis.

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.
