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.
The melting of a candle is a physical change because it is a change in state from solid to liquid without altering the chemical composition of the candle.
The melting of a candle is a physical change. It involves a change in state from solid to liquid due to the absorption of heat energy, without any change in the chemical composition of the candle wax.
The hardening of candle wax is a physical change. This is because the wax simply changes from a liquid to a solid state without any change in its chemical composition.
When alcohol and mercury boil, they both change from a liquid to a vapor/gas.
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.
The solid wax of the candle melts, and eventually vapourises, then burns and becomes a gas.
This change of state is called condensation.

melting
The energy needed to change the state of matter of a candle is primarily in the form of heat energy. When the candle is lit, the heat energy from the flame melts the candle wax, causing it to change from a solid to a liquid state. Further heating vaporizes the liquid wax, transforming it into gaseous wax molecules that combine with oxygen to produce light and heat energy.
The change of state is Melting. Solid to liquid is melting. E.g. ice to water
The hardening of candle wax is a physical change. This is because the wax simply changes from a liquid to a solid state without any change in its chemical composition.
When alcohol and mercury boil, they both change from a liquid to a vapor/gas.
When a candle is lit, the wax melts into a liquid state due to the heat from the flame. The liquid wax is then drawn up the wick through capillary action and vaporizes into a gas, which is what burns to produce the flame.
When a candle is lit, the solid wax melts and turns into liquid wax. As the candle burns, the liquid wax is drawn up the wick by capillary action and evaporates, creating a gas that then burns and produces heat and light.
