Why doesn't wood turn to liquid when it burns?
wood burning is a combsution reaction, so it produces carbon dioxide, heat and some water vapor, but not liquid water.
What chemical change needs heat?
burning of wood
What is the observable change for burning a log?
The observable change for burning a log is the production of heat, light, and smoke.
When wood is burned heat ash and smoke are produced . Describe this reaction and explain what type of change is occurring?
The reaction of the wood burning is Oxidation as wood combines with air, the type of change that is occurring is a chemical change.
What evidence suggests an energy tranformation has taken place when wood in burned?
The heat coming off a fire, whereas wood does not emit heat by itself. Also the change in colour and shape of the wood.
When wood is burned heat ash and smoke are produced describe this reaction and explain what type of change is occurring?
Burning wood is a chemical reaction where the wood combines with oxygen in the air to produce heat, ash (carbon residue), and smoke (gaseous byproducts). This is a chemical change because the wood undergoes a chemical reaction to form new substances.
Two examples of changes in matter?
Melting of ice to form water is a physical change in matter as the substance changes from solid to liquid state without altering its chemical composition. Combustion of wood to produce ash, heat, and light is a chemical change in matter as the wood undergoes a chemical reaction to form new substances.
Burning wood in the fireplace is an example of what kind of change?
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.
When a piece of wood burns it makes heat light and ash. what type of change is it?
When a piece of wood burns, it undergoes a chemical change. This process involves the wood reacting with oxygen in the air, resulting in the production of heat, light, and ash. Unlike physical changes, which do not alter the substance's chemical composition, combustion transforms the wood into different substances, indicating a permanent change.
Does wood change to a liquid?
nope, after being burnt so long the wood may only burn and give off certain gasses/chemicals, but because of the way the atoms and chemicals are structually built with its protons and neutrons, the wood will not turn into liquid
What is the action of a solid changing to a liquid state usually through the application of heat?
If you use enough heat, anything that won't either sublime, which is to go directly from solid to gas (dry ice, wood, some inks), or ignite, which is to catch fire, will change from a solid to a liquid.
Explain why burning of wood and cutting it into small pieces are considered as two different types of change?
burning of wood is a chemical change as it produces heat and cutting it into small pieces is a physical change as there is a change in shape and size.
