A pot of water at room temperature is placed on the burner of a gas stove and heated until 15% of the water has evaporated due to boiling.
(a) Complete it to show a temperature-time graph for the heating (including boiling) of the water.
(b) Describe the changes that take place in the kinetic and potential energy of the water molecules as the water is heated, and then when it boils.
(c) Describe the changes that take place in the kinetic and potential energy of the gas molecules as they undergo combustion in the stove.
(d) Use the law of conservation of energy to explain the graph that you have drawn.
