Answer;

Direction, speed, and distance of charged particles

The Wilson cloud chamber is used to study the direction, speed, and distance of charged particles.

Explanation;

Wilson's Cloud Chamber is the classical pattern where alcohol saturates a pad in the chamber and a vacuum pump (reversed tyre pump) is used to draw a partial vacuum to super saturate the remaining air with alcohol vapour.

The Wilson cloud chamber works by producing a super-saturated vapor, as explained by florin. When a charged particle passes by, it ionizes the molecules of the liquid, and these ions become centers for droplets, which condense around the ionization trail.

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .
