To study the effect of heat on ice by using a graph:conclusion
Answers
HEY MATE HERE IS YOUR ANSWER
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.

Answer
Most of the substances expand on heating and contract on cooling. Whereas, from the graph, it is clearly visible that water shows a distinct and peculiar behavior between 0oC to 4oC. Water, instead of expanding, contracts between 0oC to 4oC. After 4oC, it shows the normal behavior of expansion as is shown by other substances. Thus, at 4oC, water posses maximum density and minimum volume.
This behavior of water between 0oC to 4oC is known as anomalous behavior of water.
