No, they are different processes.
No. Sugar is a carbohydrate. After heating (or burning or charring) it is oxidized to carbon dioxide and water and the reaction is irreversible.

Burning a candle is an irreversible change because the wax undergoes a chemical reaction with the oxygen in the air, producing new substances like carbon dioxide, water vapor, and ash. Once the candle has been burned, it cannot be restored to its original state.
Yes as once melted you cannot get the same substance back. Think about putting butter onto your toast it changes its texture completely! thanks for that.... it is irreversible because anything that is cooked;it candt be reversed(:
The difference between reversible and irreversible is that reversible changes can be changed and irreversible changes cannot. Apart from sometimes but it usually is really hard. Also when the change is reversible no new substances are formed. When the changes are irreversible they are. Something that is reversible can be changed, something that is irreversible cannot be changed. For example, bread into toast is an irreversible reaction, because you cannot turn the toast back into bread.
No, it's a chemical reaction with O2.In physical changes the chemical formula remains the same; like ice (H2O) and water (H2O). Burning wood is something like cellulose + O2 --> CO2 + H2O
from the rain water collected ,same cloud can't be formed.so it an irreversible change.likewise ,deforestation too can't be considered asreversiblechange.
Charcoal is a form of carbon, but they are not exactly the same. Charcoal is a type of carbon that is created through the incomplete burning of organic matter, such as wood. Carbon, on the other hand, is a chemical element that can exist in various forms, including charcoal.
Burning is a chemical reaction between a substance and oxygen. Sublimation is a type of physical state change produced by changes in temperature and/or pressure; it is not a chemical reaction. Sublimation is not the same as combustion.
Cutting down a tree. shredding of paper as well as same of the irreversible change
When water is spilled onto a flame, it can cool the flame and disrupt the combustion process, causing incomplete burning of the fuel. This incomplete burning can produce soot particles that emit light, resulting in a yellow or orange color in the flame.
They arent.
