Negative pressure governs not only the Universe or the quantum vacuum. This phenomenon, although of a different nature, appears also in liquid crystals confined in nanopores. At the Institute of ...

Scientists have found the proof for a liquid-to-liquid transition in sulfur and of a new kind of critical point ending this transition. Scientists from the ESRF, together with teams from CEA and ...

The pressure caused by a column of liquid can be calculated using the equation: pressure = height of column × density of the liquid × gravitational field strength The density of water is 1,000 kg/m 3.

The movement and space between particles in a fluid affects the amount of pressure the fluid exerts. This means that the pressure in a fluid changes depending on its height, depth and temperature. The ...
