Clouding is a purely physical process of condensing vaporous water into liquid water (also freezing or sublimating it to solid ice / hail / snow) . Chemically nothing has changed (water molecules stay unchanged, still being water) only there (physical) state (this is a kind of 'condition' of matter) has changed.
Whipping egg whites is a physical change.
The moisture is just water vapor, so you are getting a phase change from liquid to gas. Phase changes are physical changes. For a vaporizer to produce a chemical change it would have to do something drastic like convert the water in to H2 and O2.
Blending air into ice cream to give it a lighter texture is a physical process. This is because air being incorporated into the ice cream does not change the chemical composition of the ingredients; it just alters the physical structure by introducing air bubbles to create a lighter texture.
This is a physical change. When water vapor in the air condenses to form clouds, it is a change in state from a gas (water vapor) to a liquid (water droplets). No new substances are formed.

Glass of water sweating is a physical process caused by condensation of water vapor from the air onto the cooler surface of the glass. It does not involve any chemical reactions.
Transpiration.
When you say that there is moisture in the air it pretty much means water in the air.It is a physical change, as no new products have been formed.

Yes, humidity in the air is considered a physical change. It refers to the amount of water vapor present in the air, which can vary with temperature and other conditions. This change in moisture content does not alter the chemical composition of water; it merely changes its state from liquid (in the form of droplets) to gas (water vapor). Thus, the process of evaporation and condensation associated with humidity is a physical change.
When you breathe in air, the process is called inhalingor inhalation.Breathing out is exhaling, and the overall process is known as respiration.
The rising of hot air over a radiator is a physical process. It is due to the difference in temperature between the heated air near the radiator and the cooler air in the surrounding environment. As the air near the radiator becomes warmer, it expands and becomes less dense, causing it to rise and be replaced by cooler air. This process, known as convection, is a form of heat transfer.
Evaporation is the process where water moves from the air to the land.
