about boiling water. If you cover the tin and allow the water and air to cool down‚ the air will cool and contract‚ lowering the pressure in the tin. If it lowers enough‚ the partial vacuum will collapse the walls of the can! The boiling point definitely reduces with air pressure. There is a famous demonstration where boiling water or coffee is drunk‚ the trick is it was in a vacuum chamber where it boiled at room temperature. The actual definition of the boiling point of water is the temperature

colloquium “Charity Water‚” by Cubby Graham. In this colloquium‚ Graham talked about 800 million people who didn’t have access to clean‚ safe drinking water. Diseases such as e. Coli‚ Salmonella typhi‚ and schistosoma were found in the water that they were drinking from. They shared the same water with the animals as well. People were also battling with leaches stuck in their throat from drinking the water. Graham talked about this one little girl from India that kept vomiting the water she was drinking

There are many factors which influenced the development of Anomalous water. Given that its influence pervades our society‚ spasmodically it returns to create a new passion amongst those who study its history.

The problem in the video is that Nestle is essentially gaining an astronomical profit from something that is not only free from our earth but they’re selling it to consumers for a substantial price. Nestle is making over a million a day stealing water and ruining our ecosystem for profit. I think it’s wrong for a company to come in and “recycle” for a profit. Not to mention‚ they’re not contributing back to the cities they DON’T pay taxes in and they’re creating hundreds of sinkholes from digging

molecule of water A chemist’s view of the world is not as narrow as one might think! Yes‚ we start with the atom‚ and then go on to the rules governing the kinds of structural units that can be made from them. We are taught early on to predict the properties of bulk matter from these geometric arrangements. And then we come to H2O‚ and are shocked to find that many of these predictions are way off‚ and that water (and by implication‚ life itself) should not even exist on our planet! But we soon
