four choices have been provided. Select the correct alternative. Anomalous behaviour of water can be demonstrated with the help of Hope's apparatus. Arrange the following steps of changes taking place in Hopes apparatus in the proper sequence.
(A) The temperature shown by the lower thermometer reaches to 4^∘C and remains constant at 4 ^∘C.
(B) Water freezes into ice at 0^∘C, and the layer of ice is formed at the top surface because the density of ice is less than that of water.
(C) The initial temperature of water is maintained at 10^∘C. The temperature of water begins to fall due to the freezing mixture at the centre and it contracts.
(D) As temperature of water falls below 4^∘C, water expands instead of contracting and its density decreases. So, water goes up from the centre portion.
(E) As density increases, the cold water goes to the bottom. The temperature shown by the lower thermometer falls.
(F) The temperature of water at the top of the vessel begins to fall till 0^∘C as shown by the upper thermometer.
(G) Being a bad conductor of heat, ice prevents the loss of heat from water below it into the surroundings.
