火系吾系物質？佔吾佔空間？

火系吾系物質？佔吾佔空間？
火唔係物質,光只係電磁波中的可見光,由於波動的振幅很高,所以帶有很多的能量,其實火的能量原本係波動能,當佢接觸到物質既時侯,波動能就會變造熱能.由於火係能量,所以係唔會佔空間既.

點解仲會有火出現？
火吾佔空間？
定系火佔據左空氣既空間？
因為火係唔佔空間,而且就算係其他物質都可以加入房入面嫁,只不過會增加左房埋面空氣既密度姐,因為密度=質量/容量.容量少左,密度就會增加.

Fire is very hot air, which radiate visible light so that you can see it. The air already exist in the room.

Why the air became hot and fire can be seen?
It is becasue the chemical reaction of burning of wood.

CxHy (wood) + O2 (oxygen) --> CO2 + H2O + energy

系火佔據左空氣既空間
因爲燃燒火需要氧气，如果這個密封既房如面無晒氧气火就燒唔到
