Solution

The correct option is C rise
As the thermometer is removed the mercury level will rise.
The temperature of ice is about $0^{o} C$ and the temperature of the room is about $30^{o} C$ . When the thermometer is removed from the ice beaker, the mercury level will rise as the room temperature is more.

Q. Why does the mercury in a clinical thermometer not fall or rise when removed from the mouth?

Q. A student sets up an apparatus to determine the melting point of ice. He takes a beaker half filled with crushed ice and dips a mercury thermometer with an initial reading of room temperature (25ºC) in such a way that the bulb of the thermometer is surrounded by ice. The correct observation obtained by the student is that :
(1) Mercury in the thermometer keeps on falling till it reads, −1ºC and becomes constant thereafter
(2) temperature falls, reaches 0ºC, then it remains constant even after the whole of the ice has melted
(3) the temperature falls in the beginning but starts rising as soon as the ice starts melting
(4) temperature falls, reaches 0ºC and remains constant only as long as both ice and water are present in it
