Physical Properties The purpose of this lab was to see how certain substances; Naphthalene‚ Toulene‚ and and 2 unknowns (one liquid‚ one solid) react with 3 different solvents. To identify the two unknowns‚ testing needs to be done to find the density of both the liquid and the solid‚ determine the melting point of the solid‚ and the boiling point of the liquid. The Physical Properties of Pure Substances Table can then be used to compare the observed results with the accurate properties from the

Water resources are sources of water that are useful or potentially useful. Uses of water include agricultural‚ industrial‚ household‚ recreational and environmental activities. Virtually all of these human uses require fresh water. 97% of the water on the Earth is salt water. However‚ only three percent is fresh water; slightly over two thirds of this is frozen in glaciers and polar ice caps.[1] The remaining unfrozen freshwater is found mainly as groundwater‚ with only a small fraction present

Water Polution definiton: Water pollution is the contamination of water bodies (e.g. lakes‚ rivers‚ oceans‚ aquifers and groundwater). Water pollution occurs whenpollutants are directly or indirectly discharged into water bodies without adequate treatment to remove harmful compounds. Water pollution affects plants and organisms living in these bodies of water. In almost all cases the effect is damaging not only to individual species and populations‚ but also to

Swain Abstract Urban stormwater non-point source pollutants are recognized as a major cause of receiving waters quality deterioration. To date most research has focused on specifying temporal variations of stormwater quality parameters which includes high uncertainties and also increases the risk of pollution control structures failure. Traditionally‚ the temporal variations of quality

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 another‚ perpendicular
