know Mercury is the first planet . Which makes it the closest to the sun. It is 57,900,000km ( 36,000,000mi.) Because Mercury is so close to the sun it has extreme temperature differences. Mercury’s surface temperatures range from -180*C to 450*C (-290*F to 840*F). Temperatures that hot can melt iron, and other metals. The dramatic temperature difference on Mercury are not only because it is so close to the sun but, also by Mercury’s surface features. The places that are the coldest on Mercury and
Mercury, historically known as quicksilver, is a unique element, whose long history and characteristics are some to be marveled at. A silvery white transition metal, mercury has a high luster, giving it a mirror-like appearance. It is the only metal that remains liquid at room temperature, yet it is not wet. This is because of its inability to be absorbed by other substances; instead, when spilled, it forms small, spherical beads. These beads are highly mobile and tremble at the slightest touch.
The Mercury Symbol My mom’s former boyfriend Rick, now known as Andrea, became a woman over a decade ago. Andrea is a transgender person whom the Mercury symbol represents. For transgender people, the Mercury symbol stands for their personal inner striving to become the gender they feel they were meant to be, equality, and pride. Happily, Andrea and my mom have remained friends since she became a woman. For many people who cross the gender line, acceptance does not always come so easily.
Mercury is inarguably one of the most, if not the most, captivating metals on the periodic table because of its unorthodox existence as well as its properties. The element mercury is a highly intricate metal that’s composition, history, and presence in modern science has keep it so prevalent for thousands of years until recently. In this essay, one will examine all components of mercury, both physical and chemical, as well as its history and modern life, in order to paint the reader a much more heightened
Mercury in the Everglades Everglades Background Information: * Established in 1947 on 1.4 million acres in southwest Florida * Sunny, Semi-Tropical Swamp Setting. Experiences near daily downpours (http://srv3sftpa.er.usgs.gov/sofl.fact.html) Mercury's Effect on the Everglades: * A small amount of mercury is found in the crust of the earth. This is not the problem. The anthropogenic mercury is the problem. The mercury that is growing dangerously in size is known as methylmercury
destroyed or created. This element is called Mercury. Mercury can be traced back to the ancient Chinese and Hindus and has been found in 3500 year old Egyptian tombs. According to Environmental Protection Agency, Mercury can be found in air, water, and soil (2014). Pure mercury is sometimes referred to as quicksilver, which is a liquid metal. Exposure to mercury or its compounds can cause Mercury Poisoning (also known as hydrargyria or mercurialism). Mercury exists in several forms. The forms are: elemental
Project Mercury Project Mercury, the first manned U.S. space project, became an official NASA program on October 7, 1958. The Mercury Program was given two main but broad objectives: 1. to investigate man’s ability to survive and perform in the space environment and 2. to develop basic space technology and hardware for manned space flight programs to come. NASA also had to find astronauts to fly the spacecraft. In 1959 NASA asked the U.S. military for a list of their members who met certain qualifications
Mercury: A toxic poison No other metal better illustrates the diversity of effects caused by different chemical species than does mercury. On the basis of chemical speciation, there are three forms of mercury: elemental, inorganic, and organic compounds. The major source of mercury is the natural degassing of the earth's crust, including land areas, rivers, and the ocean, and this source is estimated to produce on the order of 2700 to 6000 tons per year. The total man made release into the
Humans and animals have been exposed to one or all forms of mercury, but the toxic effects can vary depending on the person or the animal. The toxic effects can also vary on the amount of exposure, what type of chemical form the mercury is in, and where the exposure is. Humans and animals weight different amounts and are different in height. The smaller the mammal the more the symptoms of mercury poison will be seen, and the toxic effects. Other factors involved are family genes, diet, lifestyle
conscious person should think of heavy metals such as lead, cadmium, and mercury. The most common metal to come in contact with humans, with possibly the most serious effects, is mercury. Mercury is a natural substance that can be found in the environment. It is the only common metal that is a liquid at room temperature, but at high temperatures it can evaporate into a colourless, odourless vapour. For years, this type of mercury has been used in products such as thermometers, switches, batteries, jewellery
you put on your skin-care and makeup? We all know mercury is often used in all kinds of measuring equipment. Mercury is a highly toxic element that is found both naturally and as an introduced contaminant in the environment (EA, Alhibshi). However, this element is even used in cosmetic products as well. Scientists testing on 73 different cosmetics including face and lip products have found that 44% of face creams and 43% of lipsticks have mercury (Greenfield, Paige). Not only does it damage our skin
Mercury Pollution Imagine that every fish you have been eating and every fish on the market is contaminated with mercury; would you want to take action to improve this situation in order for yourself and everyone else to have healthy fish to eat? Most of the fish today are exposed to mercury, and mercury toxicity threatens the health of everyone who eats fish. Mercury pollution has been a well known ocean pollution for many years, and United States remain to be one of the top nations with the most
planet closest to the sun is Mercury. Therefore, Mercury is the hottest planet. Mercury’s surface is cold. However, in the daytime Mercury can get as hot as 840 degrees fahrenheit, which is 450 degrees celsius. During night time the temperature can decrease to 275 degrees fahrenheit, or -170 degrees celsius. Mercury is the smallest planet. Mercury is the quickest planet to move around the sun. Its speed is approximately 112,000 mph along its elliptical orbit. Mercury can move around the sun in 88

Some overwhelming metals incorporate: • Lead (Pb) • Mercury (Hg) • Chromium (Cr) (in spite of the fact that just the structure Cr(vi) is dangerous) • Zinc (Zn) • Copper (Cu) • Arsenic (As) • Nickel (Ni) • Cadmium (Cd) A few of these components are necessary for human health, and are useful when taken into the form in nourishments or as supplements at suitable, low levels. Alternately, cadmium, lead and mercury have no known living capacity and are lethal to people. Dis...
The spaceship has as much power as a gamma ray, large mass but so small in size. It burst with energy and as all the machines screamed with whirring of the continuation of the controls I spontaneously pressed the go button hoping it would recognize it’s righteous owner. Pain demands to be felt I whispered to the main gears of the spacecraft. After traveling in warp speed the time machine had lost most of its vigor. Soon I sat down and stood up repeating the pattern numerous times. As I stood up I
Mercury - surface geology Mercury is a very gray planet, which houses no living creatures or any ‘life’ in General. Mercury's surface is covered in impact craters, basaltic rock and smooth plains, many of them caused by what they believe is flood volcanism. Other features include vents which seem to be the cause of magma-carved valleys, often-grouped irregular-shaped, termed "hollows" that are believed to be the cause of collapsed magma chambers throughout the planet. The biggest crater on mercury
process, utilized in "Mercury," is of far greater interest than the almost direct missive from Lawrence used in "Insouciance," that flatly states his view of what "living" really is. For not only must we discover the meaning; we must also decide whether our interpretation is really Lawrence's intent--perhaps we have confused some inadvertent seepage of Lawrence's personnel venom with his intended meaning. It is a risk we will have to take as we analyze works such as "Mercury". Instead of condemning
I’d first like to discuss the four closest planets to the Sun, Mercury, Venus, Earth, and Mars, also known as terrestrial planets. These planets are different from Jovian planets, mostly because of their solid surfaces. However, these are not the only explanations for the distinctions between the Jovian and Terrestrial
was the first space mission to be sent to Mercury. Before this launch, very little was known about the planet. Because of the little knowledge about the innermost planet, the discoveries scientists uncovered in this mission shocked them. But because scientists became curious, this eventful mission blasted off. Mariner 10 was the most eventful Mercury mission because of the challenges faced in space, the facts that were discovered about Venus and Mercury, and the current state of the spacecraft. The
been used for over a hundred years to fill in cavities where there has been decay. The question many have is “what is dental amalgam?” Dental amalgam is a mixture of materials containing powdered alloy, metals and mercury. There have been some concerns, however about the safety of this mercury containing filling material. According to the Food and Drug Administration, amalgam is in the same class as gold and composite fillings and does not pose the safety concerns as once thought. Compared to other dental
