A student playing around with fluids and magnetic materials in the lab may have accidentally found an "exception" to the laws of thermodynamics, according to the authors of a new paper based on his ...

Liquids, like water or oil, do not have a fixed shape and ... Different substances have different melting points and boiling points. For example, sodium chloride (table salt) has a melting point ...

The units of density depend on the units used for mass and volume. The most commonly used units are grams per cubic centimetre (g/cm³) or kilograms per cubic metre (kg/m³). These balloons are ...

In the second class of question, we explore other examples of liquids that exhibit density minima, and ask what their behaviour can tell us about water. Regarding the first question, reports on ...

In soils, water is a major driver of biogeochemical processes (Figure 1). Chemical reactions that control soil formation and weathering reactions occur almost exclusively in liquid water (Lindsay ...
