Why Ice Melts Faster on Asphalt Than Grass
为什么冰在沥青上比在草地上融化更快
-
Asphalt absorbs more sunlight than grass does.沥青比草地吸收更多阳光。
-
It heats up quickly and passes warmth to the ice above.它升温快，并将热量传递给上方的冰。
-
Grass reflects light and stays cooler under the same sun.草地反射阳光，在同样日照下更凉爽。
-
Dark surfaces like asphalt hold heat longer at night too.沥青等深色表面夜间也更长时间蓄热。
-
This is why icy roads melt faster than lawns in spring.因此春季结冰的道路比草坪融化得更快。
-
Engineers use this idea to design safer winter sidewalks.工程师利用这一原理设计更安全的冬季人行道。
-
Light-colored materials help reduce unwanted melting in cities.浅色材料有助于减少城市中不必要的冰雪融化。
