Name: Tom Flannigan Title: Physical and Chemical Properties Purpose: To investigate the chemical properties of pure chemical substances. To investigate the physical properties of pure chemical substances. Procedure: For this lab we used four test tubes and poured equal amounts of a substance in each test tube. We then observed the color and odor. We then heated the substance and recorded the observation. The next tube we added cold water and observed the effects‚ then we heated it

Water is the most abundant molecule on Earth’s surface. It is essential for life on Earth. The unique properties of water makes life possible on earth. One property of water is surface tension. Water has a surface tension 2 – 4 times the surface tension of most organic liquids. Surface tension is highest for pure water. This enables insects called neuston to walk and live on the surface of water in low-nutrient water bodies‚ where they would starve if immersed in the water. This anomaly permits

INTRODUCTION Intellectual property surrounds us in nearly everything we do‚ at home‚ school; work‚ at rest and at play. No matter what we do‚ we are surrounded by the fruits of human creativity and invention. The importance of protecting intellectual property rights has received heightened recognition through the increase in world trade. It is estimated that billions of dollars of business is lost due to illegal counterfeiting. Between five to eight percent of all goods and services sold worldwide

What properties differentiate human language from all other forms of signaling and what properties make it a unique type of communication system? There have been a number of attempts to determine the defining properties of human language and different lists of features can be found. The following is a slightly modified list of features proposed by the linguist Charles Hockett: 1. Arbitrariness. It is generally the case that there is no ’natural’ connection between a linguistic form and

Medicinal Plants and Anti-oxidant Properties. An antioxidant can be defined as “any substance that‚ when present in low concentrations compared to that of an oxidisable substrate‚ significantly delays or inhibits the oxidation of that substrate” (Young and Woodside‚ 2001). It is well known that oxidant by-products of normal metabolism such as free radicals and reactive oxygen species (ROS) in excess can cause extensive damage to DNA‚ proteins‚ and lipids. Under stress‚ the body produces more ROS

Property Law‚ The Inside Look Azrielle D. Washington July 20‚ 2014 LSTD506 “Property law has long played a central role in political and moral philosophy. Philosophers dealing with property have tended to follow the unanimity that property has no special content‚ but is a protean construct; a mere placeholder for theories aimed at questions of distributive justice and efficiency” (Joel Feinberg & Hyman Gross‚ Philosophy of Law (1975). Until recently there has been a relative absence of serious
