例1“缥缈的雾,晶莹的露,凝重的霜,轻柔的雪,同样的水分子,装扮着我们生活的时空”．这是一首描述物理现象的抒情诗,对这首诗中所描述的物理现象理解正确的是( ) (A)“缥缈的雾”是汽化现象．(B)“晶莹的露”是液化现象．(C)“凝重的霜”是凝华现象．(D)“轻柔的雪”是熔化现象．(06年江西)分析早晚温差大,白天蒸发的水蒸气在晚上降温后液化成小水珠,若空气中有较多的尘埃,小水珠就以浮尘为凝结核,浮在空中形成雾;若液化的小水珠附着在花草树木上,就形成
Example 1 “The hazy fog, the crystal clear dew, the dignified frost, the soft snow, the same water molecules, dress up the time and space of our lives.” This is a lyric poem that describes the physical phenomenon. The correct understanding of the physical phenomenon described in this poem is () (A) The “fog of haze” is the phenomenon of vaporization. (B) The “crystal clear” is a liquefaction phenomenon. (C) “Double Cream” is a desublimation phenomenon. (D) “Soft snow” is a melting phenomenon. (Jiangxi, 06) Analyze that there is a large temperature difference between day and night. Evaporation of water vapor during the day liquefies into small droplets after cooling in the evening. If there is more dust in the air, the small droplets of water will be condensed with the floating dust and form a fog in the air. If liquefied small water beads adhere to the flowers and trees, they form
