  • Specific Heat Boiling Point
    1,047 words
    The purpose of this lab was to determine the specific heat of two different metals. In order to do this, specific directions were executed in order to discover the specific heat. First, we needed to obtain and record the weight of the Styrofoam calorimeter cup. Next, we filled the cup 2 / 3 full with cool tap water and recorded the temperature of the water. After this was done, we filled a glass beaker half full with water and placed it on a hot plate in order to have the water reach boiling poi...

  • Nitrous Oxide Liquid Nitrogen
    551 words
    Nitrogen was isolated by the British physician Daniel Rutherford in 1772 and recognized as an elemental gas by the French chemist Antoine Laurent Lavoisier about 1776. Properties Nitrogen is a colorless, odorless, tasteless, nontoxic gas. It can be condensed into a colorless liquid, which can in turn be compressed into a colorless, crystalline solid. Nitrogen exists in two natural forms of isotopes, and four radioactive isotopes have been artificially prepared. Nitrogen melts at - 210. 01 C (- 3...

  • Parts Per Million Degrees Centigrade
    410 words
    Uranium is a silvery-white element possessing a very radioactive and oxidizing character. Uranium retains a density of 19. 07 grams per cubic centimeter and a melting point of roughly 1, 132 degrees centigrade. With a boiling point of approximately 3, 818 degrees Celsius uranium is not an easy element to get to a melting or boiling point. The Periodic Table says that uranium has 92 protons and 146 neutrons thereby acquiring a atomic weight of 238 atomic mass units. Uranium burns readily in air a...

  • Oil And Gas Earths Crust
    1,469 words
    Petroleum also known as crude oil, naturally occurring oily is a bituminous liquid composed of organic chemicals. Petroleum means rock oil, from the Greek petros (rock) and oleum (oil). It occurs in the earth in liquid, gaseous or solid forms. The term is usually restricted to the liquid form, commonly called crude oil but as a technical term it also includes natural gas and the viscous or solid form known as bitumen. Petroleum is a complex mixture of organic liquids consisting of hydrocarbons (...

    Properties of Water Water is essential for life as we know it on earth. It is used by plants and animals for basic biological processes which would be impossible without the use of water. The origin of all life can be traced back to the water in the Earths precambrian seas. Water is also the universal solvent. It reacts with more elements and compounds than any other substance known to man. Water is a polar molecule made up of on atom of hydrogen and two atoms of oxygen. It is attracted to itsel...

  • Kinetic Energy Atmospheric Pressure
    1,356 words
    To define matter, one would say that it is something that occupies space and has weight. Matter naturally occurs in three phases: solid, liquid, and gas. Changing from a solid to a liquid, liquid to gas, etc. can be referred to as a change of state. Changes of state (or phase) effect our everyday lives. This chapter on changes of phase should actually be called Energy Transfer. The whole basis on changing a substances state is that it is using energy to get from one state to another. To understa...

  • Middle Class Income Ny Random House
    2,059 words
    Throughout the past century, the middle class has emerged as a vital part of the North American psyche. Even today, many people classify themselves as a part of the middle class, regardless of their actual income level. However, this perception is incorrect. In the past 20 years, the middle class has been declining, primarily as a result of past political interventions and job polarization throughout North America. The subject of middle class is very controversial, and depending on how it is def...

  • Surface Of The Water Hydrogen Bonds
    984 words
    Water is the most important substance in our evolution and our daily lives. Without water, life as we know it would not have been possible. This essay will examine the water molecule in order to ascertain how it brought about Earths thriving ecosystem and how important it is to us today. Each water molecule consists of one oxygen atom and two hydrogen atoms. The oxygen atom (or the apex of the water molecule) bears a slight electronegative charge while hydrogen possesses a more positive one 1 (f...

    Aim: Dunder Experiments Experiment 1. Aim: To find the PH of Dunder. Materials: -Crucible -Filtrated Dunder -Universal Indicator -Eyedropper Method: A small amount of filtrated Dunder is placed in the Crucible. A few drops of Universal Indicator are then dropped onto the Dunder with the Eyedropper. The mixture will then change to colour corresponding to the Dunder's PH. Results: In this Experiment the PH of the Dunder came up as 4. This showed that Dunder is considerably acidic. Experiment 2. Ai...

  • Carbon Atom Molecular Formula
    2,405 words
    3. 2 Lots of carbon compounds seem to be isomers. What is an isomer? In organic chemistry, there are many examples of different compounds which have the same molecular formula as each other, but different arrangements of the atoms in their molecules, (different structural formulae). These compounds are said to be isomers of one another. Isomerism also occurs in inorganic chemistry, but it is less common. There are two types of isomerism common in organic chemistry: structural isomerism and stere...

    Kinetic Theory? All matter is made up of particles which are in constant motion. Solids · Fixed shape and volume · Particles are held together by relatively strong forces, and are incompressible · Particles do not have free movement, but can vibrate about fixed positions · An increase in temperature will give the particles more energy, the amplitude of vibration increases, therefore the solid expands Liquids · No fixed shape, but a fixed volume · Particl...

  • Earths Atmosphere Boiling Point
    469 words
    Neon was discovered in 1898 by British chemists Sir William Ramsay and Morris W. Travers as a component of the most volatile fraction of liquefied crude argon obtained from air. Upon applying an electric current to it, the chemists found that it had an orange glow, and they decided that it was not argon, but rather a new element altogether. Neon is not a very common element, but the places it is most abundant in are the earths atmosphere, and trapped within rocks in the earths crust. The place w...
