Question

Name the apparatus used to experiment anomalous behavior of water

Answer 1

1.  Thermometer B.  It is because, as the water in the region of freezing mixture, falls in temperature, its volume decreases, its density increases and hence it sinks down.

2.  Thermometer B. The temperature of thermometer B stops registering any fall in temperature. the lowest temperature recorded is 40C.

3. It is because when water attains a temperature of 40C, its density is maximum.  Thus, it just settles down and cannot rise up.

4.  It is because, when the temperature falls below 40C, the water starts expanding, its density decreases and hence it moves upward.  Thus, thermometer A continues registering fall in temperature.
