Aims of the experiment:
a.To study the temperature change when ice is heated to steam;
b.To learn how to plot the data in the form of a line graph for better understanding of how the different variables influence each other and how to interpret the data. (The independent variable is the cause. Its value is independent of other variables in the study. The dependent variable is the effect. Its value depends on changes in the independent variable.)
Different states of water:
•Melting (water in a solid state, ice to water in a liquid state) - This occurs when the internal energy of the solid increases, typically by the application of heat or pressure, which increases the substance's temperature to the melting point.;
•Boiling (water in a liquid state to steam, water in a gas/vapour state) - The action of bringing a liquid to the temperature at which it bubbles and turns to vapour or steam;
•Condensation (water in gas/vapour state to water in a liquid state) - Condensation is the process where water vapour becomes liquid;
•Freezing (water in a liquid state to ice, water in a solid state) - Freezing is a phase transition where a liquid turn into a solid when its temperature is lowered below its freezing point.
