Depends on how fast you are stirring..... Friction from very vigorous stirring could be one answer, but while this is a real phenomemon, it is unlikely ot be significant in most cases. Another answer is that an exothermic chemical reaction is taking place between the two chemicals in the beaker.
This is a chemical reaction known as an exothermic reaction, as it releases heat. In this reaction, the zinc reacts with the hydrochloric acid to produce zinc chloride and hydrogen gas.

The beaker gets its name from its resemblance to a cylindrical drinking cup or drinking vessel. Its name is derived from the Old English word "becere" which means "drinking vessel."
The chemical in marijuana that gets you high and can be addictive is delta-9-tetrahydrocannabinol (THC). It acts on the brain's reward system, leading to euphoria and heightened sensory perception. Continued use of THC can lead to dependence and addiction in some individuals.
The active chemical in marijuana that produces psychoactive effects is delta-9-tetrahydrocannabinol (THC).

Not necessarily. The cooling effect could also arise from mixing chemicals that absorb heat when mixed with each other, even though they do not react. The cooling could, of course, also indicate a chemical reaction.

The most common reason is that the solids are absorbing water in sufficient volume to cause a notable change in volume, without dissolving or losing their appearance as solids.
A solid is as solid as solid gets. Liquids freeze and become solids. Solids become denser solids.
He gets out again but soon after he is making more trouble
Most solids expand as they increase in temperature and contract as they get colder. Interestingly, water after it freezes will start to expand as it gets even colder.
If it gets bad, tourists will stop coming.
it gets really bright.
When solids soak liquids up, the molecules of the liquid become entrapped in between the particles of the solid . A good example is how bread gets wet.
