please answer ☝️
​

Answer 1

Answer:

Method:-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).

Answer 2

Answer:

Initially, both the thermometers show the same reading, say 12 ºC. As the trough is filled with the freezing mixture, the water in the central portion of the jar loses heat energy and gets cooled. Its volume decreases and density increases. As a result, the denser layers of water in the central portion move downwards, displacing the lighter layers of water there towards the central portion. This forms a convection of water. Due to this convection, thermometer T1 near the bottom shows a rapid fall in temperature till it reaches 4 ºC. At 4 ºC, the density of the water in this part of the jar is maximum.
