Xiao Ming found in the kitchen that 1 after the water in the pot boiled, a ball appeared above the

(1) A cloud of "white gas" emerges above the spout This "white gas" is essentially the liquefaction of the water vapor emitted from the spout when it is cold, forming small droplets;

2) The phenomenon of liquefaction occurs when the water vapor is cold at high temperatures, and at high temperatures, the water vapor does not liquefy, it is still colorless water vapor, so we can't see anything

After the water vapor leaves the spout for a certain distance, it liquefies due to cold; the formation of "white gas";

After the "white gas" rises and disperses into the dry air, the small droplets will vaporize again, forming water vapor and dissipating in the air;

3) When cooking on the stove, before the flame is extinguished, the ambient temperature is high, the degree of water vapor liquefaction is small, and the "white gas" formed is less; After the flameout, the ambient temperature decreases, the water vapor liquefies a lot, and the "white gas" increases; Therefore, A is the picture after the flame is extinguished;

So the answer is: (1) small droplets; (2) High; Liquefy; Liquefy; Vaporization; (3) A
