When an object or liquid blocks the throat.
No. It's just a change of state.
Cream curdles in coffee due to a reaction between the acidity of the coffee and the proteins in the cream. This reaction causes the proteins to clump together and separate from the liquid, resulting in a curdled appearance.
Yes, this is a chemical reaction in the sense that a lowering of the temperature causes fat to move from a more liquid form to a more solid form.
Juice is not a reaction; it is a liquid mixture.
The epiglottis is a small flap of tissue at the base of the tongue that prevents food and liquid from entering the windpipe (trachea) during swallowing. It covers the opening of the trachea to direct food and liquid into the esophagus, helping to prevent choking.
Evaporization is an endothermic reaction which causes a substance to be released into the air. This is typically associated with the change from one state of matter to another like liquid to gas.

The liquid from instant ice packs solidifies due to an exothermic chemical reaction that absorbs heat from the surrounding environment, cooling it down rapidly. This reaction usually involves the dissolution of salts in water, causing the solution to reach a lower temperature and freeze into a solid form.
There is a chemical reaction between mercury and aluminum, forming what is known as an amalgam.
The evaporation of the liquid by heating.
It's called the epiglottis. Epiglottis, it is referred to as the 'guardian of the airways'.
