Combustión – ¿Sabías que?

The video explains the process of how a candle burns. Initially, the wax melts and is absorbed by the wick. As it reaches the flame, the liquid wax heats up and transforms into gas. This gas serves as fuel, reacting with oxygen in the air to sustain the flame until all the wax is consumed.

What happens to the wax when it melts?

• It solidifies immediately.

• It changes color.

• It travels up the wick.

• It evaporates into the air.

What occurs when the liquid wax reaches the flame?

• It extinguishes the flame.

• It changes into gas.

• It turns into a solid.

• It cools down.

How does the gas formed from wax contribute to the candle burning?

• It acts as a coolant.

• It absorbs oxygen.

• It creates a barrier.

• It serves as a fuel.

What role does oxygen play in the burning of a candle?

• It extinguishes the flame.

• It reacts with the gas to sustain the flame.

• It melts the wax.

• It solidifies the wax.

What happens when there is no wax left in a candle?

• The candle stops burning.

• The wax regenerates.

• The flame changes color.

• The candle burns brighter.
