Illustrate physical phenomena in nature and life with examples. The more, the better. Urgent need! !

(1) In summer, the beer bottle taken out of the refrigerator "perspires": water vapor liquefies into small water droplets when it is cold and sticks to the bottle.

(2) Frozen flowers on windows in winter: condensation of water vapor.

(3) Wake up in the morning and see fog: the phenomenon of water vapor liquefaction in the air.

(4) Frozen clothes will dry out in winter: sublimation of ice.

(5) The boiling point of water is different at different time and place: the difference of atmospheric pressure.

(6) Water can only boil jiaozi white, and oil can fry jiaozi yellow: the boiling point of oil is higher than that of water.

(7) Mirage phenomenon: light is deflected due to uneven atmosphere.

(8) Inverted pinhole image: straight-line propagation of light.

(9) Plane mirror can image: reflection of light.

(10) Chopsticks immersed in water are curved: light obliquely enters another medium and refracts.

(1 1) sunlight is refracted by a prism and becomes seven colors: dispersion of light.

(12) solar eclipse: the straight-line propagation of light.

(14) There is no sound on the moon: sound propagation needs media.

(13) A convex lens can image: the refraction of light.

(14) There is no sound on the moon: sound propagation needs media.

(15) See lightning first, then thunder: Light travels much faster on the earth than sound.

(16) We can measure the weight of an object with an ordinary steelyard: the lever principle.

(17) Drinking soda through a straw: squeezing at atmospheric pressure.

(18) Cooking in a pot can be cooked: heat conduction phenomenon.

(19) People and cars can walk on the ground: friction between objects.

(20) Human muscle movement: lever principle
