What is the observable change for burning a log?
The observable change for burning a log is the production of heat, light, and smoke.
What is the observable change of burning a log?
Burning a log results in the release of heat and light energy, as well as the production of ash and smoke. This process is a chemical reaction where the wood combines with oxygen to form carbon dioxide and water vapor.
What observable changes happens while burning a log?
While burning a log, you will observe flames and smoke as the wood undergoes combustion. The log will gradually reduce in size as it releases heat and light energy. Eventually, you will be left with charred ash and embers.
What observable changes are in burning a log?
All its substance goes gone it turns to ashes so it's not wood anymore and it becomes Chemical Change
What is an observable change for burning alive?

Is a burning log a mixture?

Which is not a physical change hitting a log with an axe cutting a log burning a log or hammering a spike through a log?
Burning the log is a chemical change. All of the others are physical changes.
Is burning log chemical change?
Yes.
What observable changes are there in a burning log?
During the burning of a log, you can observe flames, smoke, and glowing embers. As the log burns, it will shrink in size and eventually turn into ash. The color of the flames and the intensity of the heat can vary depending on the type of wood and the conditions of the fire.
Why does burning a log in the fireplace involve a chemical reaction while sawing a log in half does not?
Burning a log in the fireplace involves a chemical reaction because it undergoes combustion, reacting with oxygen to produce heat, light, and new chemical compounds like carbon dioxide and water vapor. Sawing a log in half is a physical change where the log is simply being cut into smaller pieces without any chemical reactions occurring.
Is burning logs a physical change?
No. Burning a log is a chemical change since the fire turns the wood into ash, water vapor, carbon dioxide, and elemental carbon.
Is burning a log a mixture?
Burning a log involves a chemical reaction where the wood undergoes combustion, producing heat, light, and ash. It is not considered a mixture as the log itself is a homogeneous material made up of cellulose, lignin, and other components that undergo a chemical change during burning.
