Electromagnetic radiation Electromagnetic radiation (EM radiation or EMR) is one of the fundamental phenomena of electromagnetism‚ propagating and traveling through space via photon wave particles‚ carrying radiant energy. In a vacuum‚ it propagates at a characteristic speed‚ the speed of light‚ normally in straight lines. EMR is emitted and absorbed by charged particles. As an electromagnetic wave‚ it has both electric and magnetic field components‚ which oscillate in a fixed relationship to one

2014 ! ! Physical and Chemical Properties! Purpose/Hypothesis:! • The purpose of this experiment is to investigate the chemical and physical properties of pure chemical substances. A property of a substance is some distinguishing characteristic. Some of the most common physical properties are color‚ odor‚ hardness‚ density‚ melting point‚ boiling point‚ and solubility in various solvents. For all of these properties‚ no chemical change takes place. Chemical properties describe the tendencies of a

Doctrine of fixtures in property law The doctrine of fixtures is applied to determine if an object is a fixture.1 This common law provides that what is annexed to the land becomes part of the land‚ “quicquid plantatur solo‚ solo credit”‚ and adopts the character of real property.2 For this to transpire all circumstances surrounding the annexation to the land are examined‚ including but not limited to the degree of annexation and the purpose of annexation.3 Through this both objective and subjective

Introduction Property development is a complex process that involve extensive planning‚ large amount of capital‚ complex activities and procedures‚ requires services from various parties and usually involves lengthy process. As a matter effect‚ it usually a high-risk investment that can influence changes in the economy and the property market itself. Poor planning on the development and parties involves will cause the project result in loss especially to the owner. However despite all the risk‚

In the world today‚ Nicotine is one of the most frequently used addictive drugs. The impact it has on society is like no other. It is one of more than 4‚000 chemicals found in the smoke of tobacco products such as cigarettes‚ cigars‚ and pipes. This addictive drug is the primary component in tobacco that acts on the brain. Tobacco can be found two ways‚ it can be dried brown leaves of various sizes or it can be a grown form of tobacco. When extracted from the leaves‚ nicotine is colorless‚ but

3.7. Dielectric Studies Dielectric properties are the complex function of bulk permittivity‚ conductivity‚ size‚ shape‚ frequency and spatial arrangement of the constituents [27]. The Dielectric complex permittivity is written as where‚ the real part εr and imaginary part ε″ are known as dielectric constant and dielectric loss accounts for the energy storage and energy loss respectively. The dielectric constant is calculated with the relation εr=Cd/εoA where‚ C is series capacitance

Colligative Properties & Osmotic Pressure (Lab – Chapter 13) Introduction: In this lab‚ we are going to observe the difference in freezing point between pure water and salt water. We will also observe the permeability of an egg shell membrane and dialysis tubing‚ acting in place of a human cell‚ when placed into a hypertonic or hypotonic solution. We will observe the changes in size‚ shape‚ and characteristic. Materials and Methods: First we begin this experiment by making an ice bath in
