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?


A The temperature in the thermometer kept increasing till the whole ice melted.
B Once the melting process started, the temperature in thermometer remained constant though the heating was on.
C There was no change in temperature throughout the experiment.
D Ice did not melt on heating. It was converted to vapours.


I think both the "b" option and the "c" option are the same, just different with the use of words right....
