Question

To study the effect of heat on ice by using a graph observation table

Answer 1

We know there are usually three types of heat used in everyday life to understand physical phenomena.
Heat , latent heat of fusion and latent heat of vaporisation.

Q = mS∆T , when substance doesn't change its phase , then it must be change their temperature. then, this temperature is directly proportional to supplied heat .

so, when we supply heat to ice , ice increase there remember from - T to 0°C .
you can see variation of temperature and heat in graph .

when substance change its phase at constant temperature is used new terms e.g,. latent heat. ice at 0°C change into water at this temperature. heat supplied to ice is known as latent heat of fusion.
here , in case of charging phase , heat is independent on temperature.
so, graph is parallel to x axis as shown in figure.

now, if we supply heat to water, temperature of water increase . then, again heat is directly proportional to temperature.

now, I think you understand how we plot graph of ice between heat and temperature
