VERY rough rule of thumb- the heavier and denser the wood WHEN DRY, the higher the heat value. Wood such as poplar, cedar, and pine are low density, and very light, and burn quickly. Heavier woods, such as oak, gum, ash and hickory, will burn longer, and give more heat.
Burning is a chemical change.
Burning is a chemical reaction with oxygen, an oxydation.
Wood Burning
Wood burning heater can be purchased at a wide variety of locations. The best places to purchase a wood burning heater is at a local hardware store or an appliance store.
The burning speed of wood can vary depending on the type of wood and its density, but generally ranges from 0.1 to 0.8 inches per minute. Thinner pieces of wood tend to burn faster than thicker pieces. Factors such as moisture content and oxygen supply can also influence the burning speed.
Energy cannot be created. (Or destroyed) Burning changes the chemical energy of the wood to heat energy and light energy.
Any wood is good for burning in a wood burner as long as it has been dried and seasoned.
Hard wood the tighter the grain the better.
Catapults are made from wood!
The burning of wood releases chemical energy stored in the wood in the form of heat and light. This process is known as combustion, where the wood reacts with oxygen to produce carbon dioxide, water vapor, and energy.
Burning wood in the fireplace is an example of a chemical change because the wood undergoes a chemical reaction to produce heat, light, and ash. This change is irreversible as the wood is transformed into new substances during the process.
Yes, the density of wood affects the rate of burning. Denser wood burns slower because it contains more material that needs to be heated up and burned off. Less dense wood burns faster because there is less material to be consumed.
