Any student who has taken an introductory chemistry lab course will remember identifying unknown substances by determining the temperature at which they melt. A student loads the mystery material into ...

A common technique in organic chemistry is to determine the melting point of a specimen. While commercial options exist, [kymyst] decided to build one with similar (or better) functionality, and ...

Like many sophomore pre-med students at Cornell, I’m obligated to take Organic Chemistry Lab. Unfortunately, I’ve never been very good with lab sections because of their impracticality (really, when ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

Ice and its changes are an important part of the water cycle. In this activity, we’ll watch the melting of ice at different temperatures and in different conditions. Safety First! Read the Science ...

The aim of our recent work on the homopolar intermolecular C-H···H-C interactions 2,3 was to use gas-phase computations to find out if, and why, those non-covalent interactions are stronger for ...

Researchers have discovered a new phenomenon of so-called metastability in a liquid phase. This state is common in supercooled liquids, which are liquids that cool below the freezing point without ...

Glaciers are melting at an alarming rate. As this cold fresh water from glacier melt enters lakes and oceans, it can have a big effect on how the water behaves — and on the fish, mammals, and other ...
