The mass of the ash is less than the original 3000 grams of firewood because during combustion, some of the wood is transformed into gases (like water vapor and carbon dioxide) that are released into the air, rather than remaining as solid mass. The law of conservation of mass still applies, as the total mass remains constant; it is just that some of that mass exits the system as gaseous products rather than remaining as ash.
You place 3000 grams of firewood into your fireplace and burn it. The mass of the ash is less than the original 3000 grams of wood placed into the fireplace. After watching the video, explain how the mass of the ash is less than than the 3000 grams originally placed into the fireplace. Does the law of conservation of mass apply to this fire? Use 1-2 sentences to explain this.
