Chemical and physical changes form a cycle when the cycle can be reversed or played through winding up in the same place as it started. Water is an excellent example of this type of cycle.
Chemical change does not occur in water cycle. There is no change in chemical structure.

The forming of the carbon elemental form is a chemical change. The deposition on the flask is likely a physical change, although it may not be any change at all (solid being the STP phase of carbon).
This is a chemical change.
It is a chemical change. because starch present in bread is converted into carbon and carbon dioxide and reverse of the process is not possible.

It is a change in physical state, which is a physical change.
But it IS a chemical change. When carbon burns in oxygen it forms carbon dioxide with the release of energy and the formation of a new substance. This is a chemical change and can be represented by the equation: C (s)+ O2(g) = CO2(g)
chemical because it is changing the state from solid to a gas in which is a chemical change
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.
It is a chemical change.

It constituen carbon and hydrogen converted into CO2 and H2O. It is the chemical change of candle
