生活中常遇到这种现象:水滴在火红的炉盖上,就像大珠小珠落进玉盘,滚动不已,而且还能翩翩起舞。这究竟是为什么呢?这就是现代物理学中著名的“莱顿弗罗斯特”现象。早在1756年就有一名叫莱顿弗罗斯特的科学家做过实验,当时他在一把烧得通红的铁勺上滴一滴水,水珠居然悬浮起来并持续30秒。水珠能悬浮起来的原因在于,当金属的温度很高时,水滴一接触金 Often encountered this phenomenon in life: water droplets in the red lid, like beads beads fall into the jade plate, rolling endless, but also can dance lightly. This is why? This is the famous “Leiden Frost” phenomenon in modern physics. As early as 1756, a scientist called Leyton Frost had experimented when he dropped a drop of water on a red-hot iron spoon, and the drops of water actually suspended for 30 seconds. The reason that water drops can float is that when the temperature of the metal is high, the water drops touch gold
