Many people‚ especially in warm or dry areas‚ own or have access to a swimming pool. While this attraction can be relaxing and fun on a hot summer day‚ it has tremendous consequences on the environment. The use of chlorine greatly affects the plants and wildlife surrounding the area. It can cause plants to wither away‚ turn yellow‚ and even die. The chlorine can cause the tissue of leaves to brown or rot. The toxicity can even cause microorganisms in the surrounding soil to die. Chlorine is also

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

The volume of the small can is 1157 cm3. Find the volume of the large can. 3. The volumes of two similar solids are 128 m3 and 250 m3.The surface area of the larger solid is 250 m2. What is the surface area of the smaller solid? 4. Triangular Prism X and triangular Prism Y are similar. The ratio of corresponding dimensions

This trial was performed to decide the percent centralizations of starch in two distinct arrangements. It showed us through the strategy utilized‚ which was osmosis (the dispersion of watered). Osmosis normally indicates on the grounds that it began to change in the mass for both the dialysis tubing loaded with the bizarre arrangement and the container of sucrose and water. Demonstrated that dissemination of water had happened over the semi-penetrable dialysis tubing. It’s checked on the grounds

1. Explain the terms area of convergence and area of origin and explain what each term reveals to an investigator. The area of convergence of an impact spatter pattern is the area the individual stains emanated from on a two-dimensional plane. The area of origin of a bloodstain pattern in three-dimensional space may represent the position of the victim or suspect when the stain-producing event took place. These areas can determine and reveal to an investigator the direction of force‚ angle of impact

The researchers note that their findings represent the subjective views of teachers and should not be seen as definitive proof that widespread use of computers‚ phones and video games affects students’ capability to focus. Even so‚ the researchers who performed the studies‚ as well as scholars who study technology’s impact on behavior and the brain‚ say the studies are significant because of the vantage points of teachers‚ who spend hours
