No, dissolving solutes in a solvent is always a physical change!
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).
A type of change that does not occur in the water cycle is the transformation of matter into a different chemical element. In the water cycle, water remains as H2O molecules throughout the various processes such as evaporation, condensation, and precipitation, without changing its fundamental composition.
This is a chemical change.

The simplified chemical equation for the carbon cycle is: CO2 + H2O + light energy → C6H12O6 + O2 This equation represents the process of photosynthesis where carbon dioxide and water are converted into glucose and oxygen with the help of sunlight.
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)
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.

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

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.
