absolute zero (-459 degrees Fahrenheit‚ 0 degrees Kelvin‚ -273 degrees Celsius) to liquid nitrogen temperatures (-321 F‚ 77 K‚ -196 C)‚ they have no electrical resistance. The temperature at which electrical resistance is zero is called the critical temperature (Tc) and varies with the individual material. For practical purposes‚ critical temperatures are achieved by cooling materials with either liquid helium or liquid nitrogen. The following table shows the critical temperatures of various superconductors:

Liquid Gold “The sounds of gunshots rang out throughout the town‚ piercing the veil of quiet like a hot knife through butter. Bushranger PJ Sebastian winced at the sound of every shot‚ keeping his fingers crossed and begging that none of the shots hit their mark. Desperately‚ he limped towards the tree line‚ as if he had any other choice in the matter‚ begging that the tall‚ menacing oak and gum trees could protect him from his assailant. Blood was pouring out of his thigh. He clutched at the wound

changes are used to describe matter. A property is a trait of matter‚ when that sample of matter is in a fixed state. There are two different types of properties: physical properties and chemical properties. A change is something that alters the properties of a substance. There are two types of changes: chemical changes and physical changes. A physical property is a property that can be observed without changing the makeup (or composition) of a substance. Some examples of a physical properties

Purpose: To Inform Topic: Chemical Warfare Intro 1) Chemical weapons are extremely toxic chemicals which differ from explosive weaponry. Middle ages and renaissance are documented to have used poisonous chemicals on individuals. Chemical warfare is use of chemical agents to kill or incapacitate the enemy. 2) Today I will inform you of different chemical agents. Since World War I‚ several types of agents have been developed into weapons. These chemical weapons include (I) Choking

The purpose of this lab is to identify the physical and chemical properties of four liquids: acetone‚ vinegar‚ hydrogen peroxide‚ and oil. By using our knowledge about the four liquids we needed to identify the components of an unknown mixture. Theoretical Background The liquids commonly found around the house such as acetone‚ vinegar‚ hydrogen peroxide‚ and oil was tested to identify the physical and chemical properties of these liquids. Acetone usually used as nail polish remover dissolves plastic

Surface Tension Properties of Liquids Introduction The purpose of this experiment is to measure and record the surface tension of water and other aqueous solutions using capillary rise method techniques and practicing lab safety. In this laboratory the surface tension of water depends on the concentration of the following solutes; NaCl‚ acetone‚ and sodium dodecyl sulfate (SDS). Intermolecular interactions as well as other phases (solid‚ or air) make a liquid exist. The data collected will show
