Answer 2

Why does the mass of burning wood decrease over time?

When wood burns, it undergoes a chemical reaction called combustion. During combustion, the wood reacts with oxygen in the air to produce heat, light, carbon dioxide, and water vapor. The process can be summarized by the following equation:

Wood + Oxygen → Carbon Dioxide + Water Vapor + Heat

As the wood burns, the carbon and hydrogen atoms in the wood combine with oxygen to form carbon dioxide (CO2) and water vapor (H2O). These gases are released into the atmosphere, while the solid components of the wood, such as ash, remain behind.

The decrease in mass of burning wood can be attributed to the loss of carbon and hydrogen atoms in the form of gases. Since the gases produced during combustion are lighter than the original wood, the overall mass of the wood decreases as it burns.

Does this contradict the law of conservation of mass?

The law of conservation of mass states that the mass of a closed system remains constant over time, regardless of any physical or chemical changes that may occur within the system. In other words, mass cannot be created or destroyed, only transformed or rearranged.

When wood burns, the mass of the system (which includes the wood, oxygen, and any other reactants or products) remains constant. Although the mass of the wood decreases as it burns, the total mass of the system, including the gases released during combustion, remains the same.

The decrease in mass of the wood is compensated by the increase in mass of the gases produced. The carbon and hydrogen atoms in the wood combine with oxygen from the air to form carbon dioxide and water vapor. The mass of these gases is equal to the mass lost by the wood, ensuring that the total mass of the system is conserved.

Therefore, the decrease in mass of burning wood does not contradict the law of conservation of mass. The law still holds true, as the total mass of the system remains constant throughout the combustion process.

Conclusion

When wood burns, its mass decreases due to the release of carbon dioxide and water vapor as gases. This decrease in mass is compensated by the increase in mass of the gases produced, ensuring that the total mass of the system remains constant. Therefore, the decrease in mass of burning wood does not contradict the law of conservation of mass.
