WebHydrogen bonding is responsible for some unusual properties of water, like its existence in liquid state over a wide range of one hundred degrees (273 K to 373 K), high heats of fusion and vaporization and its solid form (ice) being lighter than liquid water. Hydrogen bonding plays a crucial role in the structure of DNA WebMay 16, 2016 · The general explanation (which doesn't really explain much) is that the solid has a structure and, sometimes, that structure takes us more space than the average structure that occurs in the liquid. In water, ice has a definite structure where each oxygen sits at the approximate centre of a tetrahedron with two bonds to hydrogen and two …

The Density of Liquids - American Chemical Society

WebWhy is solid water lighter than its liquid form? Water contracts as it cools until about 4 degrees Celcius (about 36 farenheit). It then expands as it freezes by about 9% in volume. … WebFeb 17, 2011 · Water is liquid ice. The only difference I can think of would be the movement of molecules. Liquid ice implies that the water is cold, so the atoms probably move about slower than that of the ... how to share screen as webcam

Why density of Ice is lesser than water? - UrbanPro

WebB.) more dense as gases than as solids C.) less dense as solids than as liquids D.) most dense in the solid state Consider a sample of ice being heated from -25 degree C to +15 … WebJan 10, 2024 · Vocabulary. Ice is water in its frozen, solid form. Ice often forms on lakes, rivers and the ocean in cold weather. It can be very thick or very thin. It occurs as frost, … WebAnswer (1 of 8): I don't find it that strange. I take it as normal behaviour for ice. It is said to have a negative thermal expansion. The reason for it floating being that water expands when it is cooled below zero degrees celcius. That means that while water’s density remains constant in the w... how to share screen between mac and windows
