Diffusion is the movement of molecules from areas of high concentration to areas of low concentration. With diffusion no energy is required and it is caused by kinetic energy. The rate of diffusion can be affected by many things including temperature‚ molecular weight‚ and movement. To test the rate of diffusion a drop of dark food coloring was added to a glass of tap water and it was timed to see how long it took for the drop to reach the bottom of the glass. This procedure was repeated three

Solid Wastes Management BASURA‚ GARBAGE‚ GOMI‚ ORDURES‚ AFVAL‚ SPAZZATURA— whatever people call it‚ solid waste is a problem that must be properly managed. While it is generally understood that proper waste management helps protect human health and the environment and preserve natural resources‚ many do not realize that solid waste also impacts climate change. The manufacture‚ distribution‚ and use of products—as well as the disposal of the resulting waste—all result in emissions of atmospheric

encompasses 7‚107 islands‚ though only about 2‚000 islands are currently inhabited. With a rapidly growing population and lack of adequate disposal sites‚ solid waste has become a major problem for most medium to large – size cities. When Philippine President Gloria Macapagal – Arroyo took office in January 2001‚ the first act she signed into law dealt with solid waste management systems have posed serious health risk particularly in densely populated areas. In Manila‚ for example‚ the closure of the largest

In the Metal Gear Solid series‚ Hideo Kojima criticizes social‚ political‚ and cultural issues through video games by introducing today’s generation to fears of nuclear fallout and technological anxiety‚ the government control of information and data during the Information Age‚ and through the theory of intertwined fictional and actual history called Hyperreality. Though he is a Japanese video game developer‚ Hideo Kojima gained all of his inspiration for the Metal Gear Solid series from American
