Q. The following precautions were listed for the experiment on the determination of the melting point of ice. The incorrect precaution is :
(1) The bulb of the thermometer should be kept surrounded with crushed ice.
(2) Ice should be stirred regularly to keep a uniform temperature throughout.
(3) The final temperature should be noted by keeping the eyes in line with the level of mercury.
(4) Only the tip of the bulb of the thermometer should just touch the crushed ice.

Q. Describe an experiment to show that there is an absorption of heat energy when the ice melts.

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
