Experiment: Effect of heat on ice

Ice is put in a beaker and a thermometer placed inside the ice cubes. The ice is heated and the temperarure recorded in intervals of 1 minute.

Time(min)

Temp 0c

The results obtained can be used to plot a graph of temperature against time (min).

Sample results.



At pointAB the Solid ice is gaining heat.
At point BC the ice is melting. The heat energy supplied changes the solid ice into a liquid.
At the point CD the water formed absorbs heat and the temperature increases.
At point DE the water changes into a vapour. The heat energy supplied is used to overcome the force of attraction between the water particles.During change of state the temperature of a substance remains constant but the substance continues to absorb heat energy.The temperature remains constant because the heat energy is used to overcome the force of attraction between the particles in a substance.
