Question

Anomalous behaviour of water can be demonstrated with the help of

Hope’s apparatus. Arrange the following steps of changes taking place in the

Hope’s apparatus in the proper sequence.

A) The temperature detected by the lower thermometer reaches to 0

0C and

remains constant at 4

0 .

B) Water freezes into ice at 0

0C and as the density of ice is less than that of

water, the layer of ice is formed at the top surface.

C) The initial temperature of water is kept constant at 100C. the temperature

of water begins to fall because of the freezing mixture at the centre and it

contracts.

D) When temperature of water decreases from 4

0C to lower temperature,

water expands instead of contracting and its density decreases. So, water

goes up from the centre portion.

E) The cold water goes to the bottom, as the density increases and the

temperature shown by the lower thermometer falls.

F) The temperature of water at the top of the cylindrical jar begins to fall till

0

0C which is shown by the upper thermometer.
G) Ice prevents the loss of heat from water below it into the surroundings

because it is a bad conductor of heat.​
