Discussion Overview
The discussion centers around identifying chemicals that freeze at temperatures below 60 Kelvin, with a specific interest in those that freeze below 50 Kelvin. Participants explore resources and references for finding this information, including organic molecules and elements.
Discussion Character
- Exploratory
- Technical explanation
- Homework-related
Main Points Raised
- One participant requests a reference list of chemicals that freeze below 50 K, noting that while many organic molecules do, they are unsure of specific examples.
- Another participant suggests that Alfa Aesar has released a significant amount of chemical melting point data, which may be useful for finding relevant information.
- This second participant also mentions that for temperatures around 100 K, silanes and certain conjugated organic chemicals might be more readily available, and recalls that methane freezes around 90 K.
- A third participant recommends the CRC Handbook of Chemistry as a potential resource for this information.
- Another participant provides a link to a melting point chart for elements but notes that it does not include deuterium, which freezes at about 19 K.
Areas of Agreement / Disagreement
Participants do not appear to reach a consensus on specific chemicals that freeze below 50 K, and multiple suggestions for resources and approaches are presented without definitive agreement on the best source.
Contextual Notes
Limitations include the potential difficulty in finding comprehensive lists of chemicals that freeze at such low temperatures and the reliance on specific databases or handbooks that may not cover all organic molecules.
