freezing point or melting point of water is the temperature at which water changes phase from a liquid to a solid or vice versa. The freezing point describes the liquid to solid transition while the melting point is the temperature at which water goes from a solid (ice) to liquid water. In theory‚ the two temperatures would be the same‚ but liquids can be super cooled beyond their freezing points so that they don’t solidify until well below freezing point. Ordinarily the freezing point of water is

North Greenville University‚ I was a member and a student of the Spartanburg County School District 2. Specifically‚ I was part of the Boiling Springs community. A remote place that didn’t have much to offer at first glance; although‚ this was probably due to my birth in a crowed and industrialized city. Yet‚ during the almost decade that I have lived in Boiling Spring it has been becoming increasingly similar to the hustle and bustle that I left behind. New businesses and roads lead to families

The Slow Boiling of America by Radical Islam US Army Officer Major Nidal Malik Hasan’s attack at the Fort Hood Army base on November 5‚ 2009 killed 13 US soldiers and wounded 30 more. Eyewitness reports state before Hasan opened fire‚ he yelled “Allahu-Akbar‚” which translates as “Allah [God] is great‚” a phrase uttered by many radical Muslims in recent history just before committing similar acts of violence in the name of Allah (Allahu Akbar). As shocking as this incident is‚ it is only one

Exploring Boiling Points Introduction: Every substance has a unique set of properties that allow us to differentiate between them. These properties are classified as physical properties and chemical properties. Physical properties are those that can be determined or measured without changing the composition or identity of the substance. These properties include color‚ odor‚ taste‚ density‚ melting point‚ boiling point‚ conductivity‚ and hardness. Chemical properties tell us how the substance

Justin Davis Period 1 9/24/2012 The Bunsen Burner and Boiling Water The Bunsen Burner is a piece of laboratory equipment that produces a single flame which is used for heating‚ sterilizing‚ and combustion. The gas used in Bunsen burners can be natural gas like methane‚ or propane‚ butane‚ or a mixture of both which are all liquefied petroleum gas. The Bunsen burner was named after a man named Robert Bunsen. In 1855 Robert Bunsen invited the Bunsen burner and it is now used all over the world

Once the juice arrived in the boiling house‚ it was contained in clarifying vats and lime was added. It was then boiled in cast iron "coppers" of diminishing size. The furiously hot liquid would be skimmed and ladled into the next smaller copper until it reached just the right consistency and was diverted to a wooden trough leading to wooden flats where it was allowed to cool. The slaves who mastered the boiling stage of the refining process were some of the most highly valued workers on a plantation
