when wood burns, the ashes have different chemical properties from the wood.true or false?
True
True. When wood burns, the chemical composition of the wood changes, resulting in the formation of ashes with different chemical properties than the original wood. The combustion process involves the release of gases and the breakdown of organic compounds present in the wood, leaving behind minerals and inorganic compounds in the form of ashes.
To understand this further, you can experiment with burning wood and observing the resulting ashes. Here's a simple step-by-step process to do it safely:
1. Find a suitable outdoor location for the experiment, away from flammable materials and structures.
2. Gather some dry wood and place it in a safe fire pit or fireplace.
3. Use appropriate means like matches or a lighter to ignite the wood and let it burn.
4. Observe the process of combustion, noting the color of the flames and the nature of the smoke produced.
5. Once the fire has burned out, allow the ashes to cool down.
6. Examine the ashes and compare them to the original wood. You will notice that they have a different color, texture, and chemical composition.
This simple experiment will help you observe the chemical changes that occur during the burning of wood and understand why the resulting ashes have different chemical properties.
