- 112: Gold And Its Uses
- ... solution percolates through the heap and the cyanide dissolves the gold. This solution containing dissolved gold is then collected. Refractory ore containing carbon is roasted to over 1,000 degrees Fahrenheit, burning off the sulfide and carbon. The product of this process is an oxide ore, which is routed to the leaching circuit. Oxide ore is sent directly to the leaching ...
- 113: Life Outside Our Biosphere
- ... traces of water vapor in the upper atmosphere, but were disappointed when concentrations of sulphuric acid were discovered mixed with the water. Venus has surface temperatures of around 600 degrees Fahrenheit, and an atmosphere one hundred times as thick as the Earth's. (This produces pressure equivalent to pressure two miles under water on Earth.) These conditions project a less than ...
- 114: Global Warming
- ... certain gases that occur naturally in the atmosphere tend to trap the sun's heat. This natural "greenhouse effect" helps keep the Earth's average temperature at a comfortable 59° Fahrenheit. Without these greenhouse gases, the Earth would be about 0° F, like a deep- frozen snowball. The earth's climate is predicted to change because human's are changing the ...

Because Cesium reacts so violently with organic compounds, it is considered the most reactive of Alkali metals. There are four principle compounds that make up ...

While this is a seemingly insignificant increase, the ten hottest years in recorded human history have all occurred in the eighties and nineties. A small rise in atmospheric temperature significantly ...

- ... Agency (EPA) suggests that global temperatures are indeed rising. According to the EPA, observations collected over the last century show the average land surface temperatures have risen 0.45 degrees Fahrenheit, -0.6 degrees Celsius in the last century! Greenhouse gases may be t blame for such a rise in temperatures, according to the EPA. They also predict United States temperatures ...
