Question

name the following :
a device used to study the anomalous behaviour of water

Answer 1

Hope's mechanical assembly or apparatus is a glass barrel surrounded with a trough with freezing mixture. Gaps in the chamber at its peak and the base enable thermometers to be embedded into the water to test its temperature. After an adequate time-frame the dense water gathers at the base at a temperature of 4°C.  

Expansion of water anomaly  is a property of water where water expands instead of contracting when the temperature goes from 4°C to 0°C, and it turns out to be less thick. Regularly, fluids contract on cooling and there will be increment in its density.  

Water achieves its most extreme density at 4°C. This is due to hydrogen holding between the oxygen particles that are charged negatively and the hydrogen molecules that are charged positively, from two unique water molecules.

Answer 2

Hope's Apparatus

But as device is asked it may be else
