Wax is a solid substance and its molecules are tightly packed together. When wax is heated, the molecules of wax gains kinetic energy and move about randomly until the inter molecular forces binding them together is broken and the wax turn into liquid.

What happens when wax is heated?
The liquid wax vaporizes due the heat produced by the flame. This wax vapor near to flame burns and gives new substances like Carbon Dioxide, Carbon soot, water vapours, heat and light. This is an irreversible change. wax actually burns to give out energy and CO2.

When wax is heated it turns into liquid How are the wax molecules affected by the change of state?
The added thermal energy between the molecules gives the molecules more energy and causes them to move quickly and further apart. This added distance between the molecules causes a weakened force between the molecules and causes a state change.

What happens to the particles of a liquid when it is heated?
When a liquid is steadily heated, the particles move rapidly until many of them have sufficient energy to escape from the liquid and form a gas. This change of state is called evaporation. The liquid can also be changed to the solid state.

Can we change the state of wax?
Melting of wax is temporary and wax can settle again on cooling and turns into a solid. Hence, the change is only physical and the state of matter changes.

Which type of change is melting of wax?
No new substances are formed when wax melts. This is a physical change. However, if the wax burns, it is a chemical change. The question here is associated with melting, and so the answer is ‘physical’ change.

What happens to wax when you heat it?
The heat of the flame vaporizes the liquid wax (turns it into a hot gas), and starts to break down the hydrocarbons into molecules of hydrogen and carbon. These vaporized molecules are drawn up into the flame, where they react with oxygen from the air to create heat, light, water vapor (H2O) and carbon dioxide (CO2).

What happened to the mixtures of gravel and candle wax during heating?
Rocks partially melt, and the minerals of lowest melting points are the ones which melt and rise (they are also the least dense minerals). This can be shown by preparing a mixture of chopped wax and gravel in a metal container. When heated in front of students the wax melts and rises, whilst the gravel does not.
