Question

what is the importance anomalous behaviour of water by using hope apparatus

Answer 1

Anomalous are small particles of liquid say water which are closely packed.when a student want to make an experiment on water boiling point,when water its placed in a barrel and placed on fire,these anomalous particles of water vibrates evenly making convectional current movement of water thus enabling it to reach at ...

➦HERE IS UR ANSWER

➠➠This apparatus is used to determine the temperature at which water has the maximum density. Thick sheet metal construction with baked hammertone finish.

➠➠Hope's apparatus consists of a vertical vessel full of water surrounded round the middle by a trough of cooling ice. Two thermometers, one above and one below the trough, measure the temperature of the water. It is designed to demonstrate that water reaches its maximum density at 4 °C (39 °F).

➠➠As the water in the central part of the vessel cools towards 4 °C (39 °F) (and thus becomes denser) it sinks to the bottom of the vessel, displacing the warmer water. The lower thermometer will then read a constant 4 °C (39 °F). Further cooling towards 0 °C (32 °F) will cause the now less dense water to rise to the top of the vessel, where the upper thermometer will then read a constant 0 °C
