    • See, for water vapor to come out of the air, it has to go from a gas to a liquid, usually by condensing onto something like dust or your window glass.

      水蒸氣要脫離空氣，得從氣體變成液體，通常是通過冷凝在灰塵或窗戶玻璃等物體上。

    • These heat-trapping gases are called greenhouse gases. Carbon dioxide, water vapor and methane are all examples of greenhouse gases.

      這種積蓄熱能的氣體就叫溫室氣體。二氧化碳、水蒸氣、甲烷都是溫室氣體。

    • When it comes to Florida, very warm temperatures means that more water vapor can evaporate into the air, which means that when it does rain, it tends to rain a lot and very heavy and all at once.

      在佛羅里達州，氣溫很高意味著有更多的水蒸氣可以蒸發到空氣中，這就意味著一旦下雨，雨往往會下得很大，而且一下子就下得很猛。

    • It's not actual smoke, it's just water vapor condensing into tiny droplets as the now saturated air mixes with the cooler outside air at the top of the stack.

      這不是真正的煙霧，只是飽和空氣與煙囪頂部較冷的外部空氣混合時，水蒸氣凝結成的小水滴。
