Question

what is the important anomalous behaviour of water by using HOPE'S apparatus

Answer 1

⭐⭐⭐⭐⭐ ANSWER ⭐⭐⭐⭐⭐


➡ T. C. Hope actually verified the activity of ANOMALOUS EXPANSION OF WATER using two thermometers keeping a freezing mixture as a base for the experiment.

➡ The two thermometers recorded the variation in temperature with time in which the temperature from 4°C constantpy keeps om falling towards 0°C.

➡ At the ultimate stage, the lower thermometer (say, T2) shows the temperature 4°C at which water has the maximum density while the upper thermometer (say, T1) shows the temperature of water and ice both 0°C.

So, Anomalous Expansion Of Water gets verified.

➦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
