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.
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.
Condensation is not a process that lifts air. Condensation is the process by which water vapor changes into liquid water, typically resulting in the formation of clouds.
The humidifier putting moisture into the air is a physical change. It involves adding water vapor, which is a change in the physical state of water from liquid to gas, without altering the chemical composition of the water molecule.

The process of taking in air or water involves the contraction of muscles around the lungs or gills to expand the cavity and create negative pressure, allowing air or water to be drawn in. In mammals, this is facilitated by the diaphragm muscle contracting and expanding the chest cavity. In aquatic animals, gills create a similar negative pressure to draw water in and facilitate gas exchange.

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.
The formation of clouds is a physical change. This is because no new substances are being formed during the process; rather, water vapor is condensing into tiny water droplets or ice crystals, leading to the visible cloud formation. This change can be reversed by the evaporation of the water droplets back into water vapor.
When you breathe in air, the process is called inhalingor inhalation.Breathing out is exhaling, and the overall process is known as respiration.

Evaporation is the process where water moves from the air to the land.
Flotation relies on the physical property of hydrophobicity, which refers to the tendency of certain minerals to repel water and cling to air bubbles. In an ore flotation process, the hydrophobic minerals attach to air bubbles and float to the surface, separating them from hydrophilic minerals that remain in the water.
