Question

which activity would you do to prove that the temperature of a substance must reach the combustion point of that substance in order to ignite it?​

Answer 1

Answer:

Some substances, like magnesium catches fire and burns with a dazzling white flame when heated in air. Similarly, when a piece of per is brought near a candle flame, it burns, producing heat and light. The charcoal and coal bums in air producing carbon dioxide, heat and light.

Ignition temperature: It is the minimum temperature to which a combustible substance must be heated, before it catches fire.

Explanation: It happens because water absorbs a large amount of heat energy, which results in fall in the temperature of wood below its ignition temperature and the fire goes off.
