Question

Mention the type of thermometer that should be used to determine the melting point ice in laboratory.what should be the posion of bulb of thermometer

Answer 1

only mercury thermometer used to determine the melting point of ice in laboratory position of the bulb will be on ice.

Answer 2

The laboratory thermometer must be used to determine “the melting point of the ice in laboratory”.  

In laboratory for the determination of melting point of ice, first we have to use a glass rod to stir that can supply the heat uniformly.

The uniform distribution of heat makes an even mixture of ice and water. After that to check the temperature the bulb of the thermometer should be kept in a way that it touches only the crushed ice. There should be no contact between the thermometer bulb and the wall of beaker.
