The mass of the dust formed on burning a piece of paper is likely to be less than the original mass of the paper. This is because burning paper results in a conversion of some of the paper's mass into gases and ash, which can float away. The remaining dust would likely be a small fraction of the original mass.
yes because it changes the physical properties of it as a paper by burning
They are similar because you are producing a chemical change in both, making new substances.
because they oxygen
Burning a paper. Any change where you can't go back to the original item is a chemical change. You can't go from ashes back to a paper. Crumpling a piece of paper is a physical change because it's still a piece of paper.
The candle burning is a chemical process.

the gas from the Bunsen burner will cause the existing flame to flare and burn the entire piece of paper and your fingers - and the lab. it's difficult to blow out the burning paper.
we would the cup and the paper burn like when you put news paper on a bbq.
It is not safe to hold an ignited piece of paper because you risk burning yourself. The flame can quickly spread, and the paper can disintegrate, leading to ash falling onto your skin or clothing. It's best to avoid holding any kind of burning material with your bare hands.

Well think, if you burn a piece of paper, then energy is involved. Chemical energy is taking place when you burn a piece of paper. However, two more types of energy are also taking place. Thermal and radiant energy are also taking place because the fire burning the paper creates light (radiant energy) and it also gives off heat (thermal energy).
When a burning piece of wood undergoes chemical change, it reacts with oxygen in the air to produce new substances such as ash, smoke, and gases. The change is irreversible, and the properties of the wood are altered as it transforms into new compounds. Additionally, heat and light are often produced as a result of the chemical reaction, further indicating a chemical change.
