Sneha set up the experiment for melting of ice in a beaker and noted down the temperature 
throughout the process. What do you think she observed when the ice was melting ?
 

The temperature in the thermometer kept increasing till the whole ice melted

Ice did not melt on heating. It was converted into vapours  

Once the melting process started, the temperature in thermometer remained constant though the heating was on.
 

There was no change in temperature throughout the experiment
