Date of Experiment October 7‚ 2012 Report Submitted: October 7‚ 2012 Title: Liquids and Solids Purpose: The purpose of this experiment is to determine the boiling point of liquids and the melting point of solids. Procedure: I got all of my materials together and set up. I poured rubbing alcohol in a beaker and rubber banded it with the thermometer. I logged the last bubble that came out of the capillary tubes. After that I crushed the acetamide and carefully put it in the capillary tube

Waste Management Introduction In 1987 the World Commission on Environment and Development formulated the concept of „sustainable development‟ (United Nation 1987); this notion‚ recalling „needs‟ and „limitations‟ for present and future generations‚ implied in all decision-making a combination of economic‚ social and environmental concerns (Sales et al. 2006). In 1992 the Rio Conference confirming this idea (United Nation 1992) heralded the concept of social compatibility as a third dimension

Disadvantages of Municipal Bonds The greatest advantage of municipal bonds can be summed up in two words: tax free. The interest rates on municipal bonds may seem low compared to similar long-term securities like Treasury bills and CDs‚ but tax advantages may level the playing field. Let ’s look at some examples. If you ’re in the 25 percent bracket for 2008 federal income taxes‚ you ’d have to find a taxable security with an interest rate of 4 percent to equal the yield of a tax-free municipal bond with

Don’t Be Haste to E-Waste Electronic-waste (e-waste) has emerged as a critical global environmental health issue in both developed and developing nations. The Environmental Protection Agency (EPA) refers to e-waste as "electronic products that are discarded by consumers." More specifically‚ e-waste is a generic term that encompasses various forms of electrical and electronic equipment that may be old‚ might have reached end-of-life and most importantly cease to be of any value to their present owners

Biodegradable Waste Bio-waste is defined as biodegradable garden and park waste‚ food and kitchen waste from households‚ restaurants‚ caterers and retail premises‚ and comparable waste from food processing plants. It does not include forestry or agricultural residues‚ manure‚ sewage sludge‚ or other biodegradable waste such as natural textiles‚ paper or processed wood. It also excludes those by-products of food production that never become waste. Currently the main environmental threat from

What is e-waste? E-waste is those waste materials consisting of any broken or unwanted / obsolete electrical or electronic appliances & gadgets. If it is not carried out properly it can dangerous to the human health or to the environment. India currently produces 500‚000 tones of e-waste annually and the figure is expected to touch one million tones in 2012. However‚ India lacks a proper e-waste disposal system and it is left up to the unorganized sector to dispose of the waste. The unorganized
