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 ...

Examples of liquids include water, honey and milk. They can flow or be poured easily. They are not easy to hold. They change their shape depending on the container they are in. Even when liquids ...

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 ...

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 ...

"Over the decades, scientists have made efforts to mathematically describe the seemingly simple phenomena of liquid flow and spreading. For example, Tanner's law describes how a droplet of water ...

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 ...
