it becomes black(change in color), change in size
When paper is burned, it undergoes a chemical reaction called combustion, producing ash, smoke, and carbon dioxide gas. The cellulose fibers in the paper break down and char, while the remaining material transforms into ash consisting of mineral compounds present in the paper.
A burning candle involves both physical and chemical changes. The physical change is the melting of the wax, while the chemical change is the wax combining with oxygen in the air to produce heat, light, carbon dioxide, and water vapor.
Clamp burning is an open-air method of burning wood in a pile with limited oxygen, while kiln burning involves using a controlled environment like a furnace or oven to burn wood. Clamp burning is less controlled and produces more smoke and emissions, while kiln burning is more efficient and produces higher quality charcoal or wood products.
Both rusting and burning are forms of oxidation reactions. In both processes, a material combines with oxygen to form new compounds. Rusting typically involves the corrosion of metals, while burning is the combustion of organic materials, resulting in the release of heat and light.
Combustion of wood and rusting of iron are two examples of fast chemical changes. In combustion, wood reacts with oxygen to produce heat and light rapidly, while in rusting, iron reacts with oxygen and water to form iron oxide quickly.
You probably scream a lot.
the earth changes while they hibernate
it is calle dmetamorposis and actually you cant tell or say that it just happens
As a substance changes state, the temperature remains constant.
No, while we do not know the actual figure best current estimates are that there are around 200 billion observable galaxies.
Fish is a vertebrate that lives in water while tadpole is a larvae of amphibians. Fish therefore have observable scales while tadpoles have moist skin. As tadpoles grow they loose their gills which grow into legs.
Nothing bad really happens. You just have to let it cool down for a while. I would suggest you getting a new fan.
I would worry about stomach acid burning the esophagus. It will not stop the pregnancy, I strongly discourage the practice Joymaker rn
Sodium particularly reacts with the Oxygen in the Air while burning. Sodium + Oxygen ----> Sodium oxide
Oxygen is the oxydant in the reaction of burning.

melting any metal is physical. rusting iron is chemical
