Does it happen while you are eating and drinking? Or is it reflux from your stomach?
When an object or liquid blocks the throat.
No. It's just a change of state.
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.
A liquid on its own cannot be described as either endothermic or exothermic. The terms endothermic and exothermic are the names of two opposite process reactions. An endothermic reaction absorbs heat and and exothermic reaction gives off heat. A liquid can be involved in either an endothermic reaction or in an exothermic reaction. If you are evaporating a liquid from its liquid phase to its gas phase, then the reaction is usually endothermic and vice versa, going from the gas phase to the liquid phase, the reaction is usually exothermic.
Juice is not a reaction; it is a liquid mixture.
Convection causes liquid rock to move.
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.

Butane is a gas at normal temperature but under cold conditions it may freeze to a liquid which causes choking, and flow of gas may reduce or totally stopped.
There is a chemical reaction between mercury and aluminum, forming what is known as an amalgam.
The evaporation of the liquid by heating.
the liquid in the thermometer rises because of the surrounding heat which causes a chemical reaction wihtin the substance which makes the liquid rises. When, the liquid sinks, itn is because the air has gotten cooler
