The change of state is melting. When a candle wax is heated, it transitions from a solid state to a liquid state.
It is because the wax changes from solid to liquid and the wax can't appear in a gaseous state
The change of state in a lit candle is from solid (wax) to liquid (molten wax) to gas (vaporized wax) as the heat from the flame melts the wax and turns it into vapor that burns, releasing heat and light.
Melting wax is a physical change because it only involves a change in the state of matter from solid to liquid, without any alteration in the chemical composition of the wax molecules. The process is reversible, meaning the wax can solidify again by cooling down.
Wax vapor refers to the gaseous form of wax that is produced when wax is heated, while gaseous wax refers to the state of wax when it is in a gas form at a certain temperature and pressure. Essentially, they both refer to the gas phase of wax but may be used in different contexts.

The change of state is melting. When a candle wax is heated, it transitions from a solid state to a liquid state.
At 20 degrees Celsius, wax is typically in a solid state.

Melting is a change of state from solid to liquid. Burning is reacting a substance with oxygen, otherwise known as combustion.
The change of state in a lit candle is from solid (wax) to liquid (molten wax) to gas (vaporized wax) as the heat from the flame melts the wax and turns it into vapor that burns, releasing heat and light.
