Title: Storing chemicals at different temperatures
Post by: Curiousity on November 28, 2020, 12:30:58 PM

Hi everyone,

I have a question, why is it that when hexane, pentanol, and isopropyl alcohol are stored at the same temperature, their temperatures when measured by a thermometer are different and more specifically, lower than room temperature?

I think it has something to do with their varying heat capacities, the fact that the sealed glass test tubes they were in were poor conductors of heat, or because of evaporation inside the test tube.

Guidance would be much appreciated!

Edit:
As well as this, would the same chemicals in an unsealed container ever become room temperature?

I said no because of the fact that they will be constantly evaporating.

If they are stored properly (that is, not evaporating) they have the same temperature.
