Вода и лёд — это одно и то же химическое вещество (молекула \\(H_{2}O\\)), но в разных агрегатных состояниях. Лёд — это вода в твердой фазе, которая образуется при температуре \\(0\\,^{\\circ}\\text{C}\\) и ниже.Химический состав: И вода, и лед состоят из атомов водорода и кислорода, образующих молекулу \\(H_{2}O\\).Структура: При замерзании молекулы выстраиваются в жесткую кристаллическую решетку. Из-за этой структуры лед становится менее плотным, чем жидкая вода, поэтому он не тонет, а плавает

Unhealthy water is ready to serve. Some of you may have seen the water rebrand I did a while back, but I wanted to attack it with fresh eyes and a slightly different approach. And I like this version much more. And yes, I’m well aware that Liquid Death exists. But 100K people asked for unhealthy water and I am a man of the people 🫡

A vivid blue car is being loaded up a ramp into a superyacht during a full storm… and you already know where this is going 🌧️🛥️ One massive wave hits, the ramp snaps, and the supercar slides backwards like it’s on ice — straight off the edge into the churning water. It floats for a second… then sinks fast. The worker just turns to the camera like: “Bro… stop filming.” Brutal. #car #wave #sea #yacht #wow
