Water (H
2O) is the most abundant compound on Earth's surface, covering 70 percent of the planet. In nature, water exists in liquid, solid, and gaseous states. It is in dynamic equilibrium between the liquid and gas states at standard temperature and pressure. At room temperature, it is a tasteless and odorless liquid, nearly colorless with a hint of blue. Many substances dissolve in water and it is commonly referred to as the universal solvent. Because of this, water in nature and in use is rarely pure and some properties may vary from those of the pure substance. However, there are also many compounds that are essentially, if not completely, insoluble in water. Water is the only common substance found naturally in all three common states of matter and it is essential for all life on Earth. Water makes up 55% to 78% of the human body.

Explore some properties of water with the Amoeba Sisters! It's all about those hydrogen bonds. Terms discussed include adhesion, cohesion, surface tension, specific heat - all made possible by those amazing hydrogen bonds. The Amoeba Sisters Channel features two sisters on a mission to demystify science with humor and relevance by creating free science videos. Since one of us is a biology teacher, our videos tend to have a life science and biology focus. You can find more info about our videos, GIFs, comics, and handouts on our website on AmoebaSisters.com. We always welcome comments, but we do have our comments on "approval" only. Criticism is fine, but this is an education channel. No bad language or discriminatory comments allowed. In other words, don't put anything here you wouldn'...
This four minute animation describes the properties of water that support life. These properties include solvency, cohesion and adhesion, high surface temperature, high heat capacity, high heat of vaporization, and varying density.

In order to make sense of why it is that water is so life-giving, we have to look at what makes water so unique. Firstly, the microscopic structure of water is investigated and for this to make sense, learners have to be familiar with bonding and intermolecular forces. Perhaps you can recap these concepts briefly during the first pause in the video. Next, the properties of water are explored . These include phase changes, surface tension, cohesion, adhesion, capillarity, and heat capacity. Water truly is an amazing substance and this has to be emphasised to learners, because the majority of us take it for granted. Many of water's properties can be explained because it has unique, strong intermolecular forces called hydrogen bonding. We suggest that you stress that hydrogen bonding is not a...
Water: A Polar Molecule In this video Paul Andersen explains how the polarity of water makes life on the planet possible. Oxygen is highly electronegative and pulls the electrons closely creating a partial negative charge. The polarity of water (and the corresponding hydrogen bonds) create cohesion, adhesion, capillary action, high specific heat, and a universally good solvent. Do you speak another language?

Get your free audiobook or ebook: http://zaxo.space/sabk/35/en/B008ICENKK/book Reflecting a rich technical and interdisciplinary exchange of ideas, Water and Life: The Unique Properties of H20 focuses on the properties of water and its interaction with life. The book develops a variety of approaches that help to illuminate ways in which to address deeper questions with respect to the nature of the universe and our place within it.grouped in five broad parts, this collection examines the arguments of Lawrence J. Henderson and other scholars on the "fitness" of water for life as part of the physical and chemical properties of nature considered as a foundational environment within which life has emerged and evolved. Leading authorities delve into a range of themes and questions that span key ...
This is a project I did for my biology class, so I thought I would model it after a Vsauce video and upload it. 🤷¯\_(ツ)_/¯

https://www.iitutor.com https://www.iitutor.com Hydrogen bonding is the important attractive and orientating force in ice. It is responsible for the rather open structure that causes it to have a density below that of liquid water. This unusual property of water means that: (i) Ice can float on water. The strong orientation of hydrogen atoms to oxygen atoms in adjoining crystals results in inefficient packing in the crystal. The structure has large hexagonal holes. (ii) When ice forms in cold weather, it covers the top of the water and so insulates the water below. If ice, were denser than water, ice forming on the top of a lake would fall to the bottom and the lake would freeze solid. Aquatic life could not survive. (iii) Water pipes can split in freezing weather. Car radiators must be ...
Amazing new discoveries about the properties of water could revolutionize our world! Filmmaker and mystic ecologist David Sereda discussed some of the amazing properties of water-- it may actually have memory and consciousness, he said. Human beings are mostly made up of water and he suggested that restructured water could have healing properties on their bodies. Following up on the groundbreaking work of Masaru Emoto, Sereda exposed water to the sounds of the sun, and the water crystals changed to a beatific shape. A subject drank restructured water and their blood cells showed a healthy response, and prayer/intention directed at water can beneficially alter its structure, he detailed. Such water must be drank right away as the restructuring may be temporary, he added. Could water itse...
https://www.iitutor.com Melting and boiling points The melting point and boiling point of pure water were originally used to establish the lower fixed point (or ice point) (0°C) and upper fixed point (100°C) for the Celsius temperature scale at standard atmospheric pressure. • The melting point and boiling point of water are affected by the presence of impurities in the water. The presence of salt, for example, will lower the melting point and raise the boiling point. Ethylene glycol (‘antifreeze’/ ‘antiboil’ ) is a compound added to the water in car radiators to lower the melting point (freezing point) and raise the boiling point. • A 20% solution of ethylene glycol will lower the freezing point by 8°C and raise the boiling point by 2°C. • Motorists driving in snow areas in winter ben...

AP Biology - Biochemistry - Lesson 2: Unique Properties of Water and Polarity
Water is the key element of life, but this element that we thought we knew well may have unexpected properties and might play a role greater than we could imagine in our tree of life. That is the belief shared by the advocates of a surprising theory called "water memory". For Prof. Luc Montagnier, water has the hability to reproduce the properties of any substance it once contained. Water would have the hability to retain a memory of the molecules properties. What if alzheimer, parkinson, autism, HIV and even cancer could be treated thanks to this controversial theory?
