Instructional Resources

Background:

Heat is a one of the form of energy. Sun is the main source of heat energy. Whenever an object at a higher temperature is brought into contact with an object at lower temperature heat energy is transferred from the object of higher temperature to the object of lower temperature. The transfer of the heat energy would continue till both objects attain the same temperature.

Materials:

Handle, match box, metal spoon and glass of water.

Procedure:

Glass of cold water is taken. The metal spoon is heated by lightening handle. Put the heated metal spoon into the glass of water. After some minutes check the temperature of the water by touching the spoon and water. We know that the temperature of the spoon is raised at the same time the temperature of the metal spoon is reduced. From these activity we conclude that heat is a form of energy and it is transferred from hotter substance to colder substance until the temperature of the both object will be the same.
