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:

During all this‚ concentration camps were being made. A concentration camp is a place where large numbers of people‚ especially political prisoners or persecuted members of a minority‚ are imprisoned in a small area with inadequate facilities‚ sometimes to provide forced labor or to await mass execution. Many of these concentration camps later became death camps for Jews. One of the most infamous concentration camps was Auschwitz because it was the largest of all concentration camps. In these

separating a liquid mixture of suspended particles into clear supernatant liquid and denser slurry having a higher concentration of solids. This is usually accomplished by allowing the particles to settle through the force of gravity‚ mechanically using centrifugal force‚ or electrostatically using an electric current. Continuous sedimentation tanks are usually used in wastewater treatment facilities to separate suspended particles from wastewater. This experiment aims to determine the effect of initial

Concentration Camps There were many social‚ political‚ and economic causes of WWII. A political cause was the treaty of Versailles. The treaty of Versailles was when we forced Germany to take the blame for WWI. If they didn’t sign the treaty‚ Germany would face invasion. As Germany did not start WWI‚ they felt it was unfair.
