Osmium Facts Six additional manmade isotopes are known. Properties: Osmium has a melting point of 3045 +/- 30 °C, boiling point of 5027 +/- 100°C, specific gravity of 22.57, with a valence usually +3, +4, +6, or +8, but sometimes 0, +1, +2, +5, +7. It is a lustrous blue-white metal. It is very hard and remains brittle even at high temperatures. Osmium has the lowest vapor pressure and highest melting point of the platinum group metals. Although solid osmium is unaffected by air at room temperature, the powder will give off osmium tetroxide, a strong oxidizer, highly toxic, with a characteristic odor (hence the metal's name).

- Common Gases at Room Temperature. There are several patterns in the table above. Common gases at room temperature include both elements (such as H2 and O2) and compounds (such as CO2 and NH3). Elements that are gases at room temperature are all nonmetals (such as He, Ar, N2, O2, and so on). Compounds that are gases at room temperature are all covalent compounds (such as CO2, SO2, and NH3) that contain two or more nonmetals. With only rare exception, these gases have relatively small molecular weights.

It's Elemental History and Uses: Osmium and iridium were discovered at the same time by the British chemist Smithson Tennant in 1803. Osmium and iridium were identified in the black residue remaining after dissolving platinum ore with aqua regia, a mixture of 25% nitric acid (HNO 3) and 75% hydrochloric acid (HCl).

- Osmium is the least abundant stable element in the earth's crust and is the densest stable element. It is found in the alloys osmiridium and iridiosmium and as an uncombined element. Osmium was first discovered by Smithson Tennant in 1803.his compound forms spontaneously when pure osmium metal is in contact with air, and is both volatile and extremely toxic, and thus the pure metal is rarely used. Osmium is, however, the most dense naturally occurring element and imparts hardness when used in metal alloys.

Liquid Elements - Elements That Are Liquids Near Room Temperature There are two elements that are liquid at the temperature technically designated 'room temperature' or 298 K (25° C) and a total of six elements that can be liquids at actual room temperatures and pressures. Elements That Are Liquid at 25°C. Room temperature is a loosely defined term that can mean anywhere from 20°C to 29°C. For science, it's usually considered to be either 20°C or 25°C. At this temperature and ordinary pressure, only two elements are liquids.

PC Operating Temperatures: How Hot Is Too Hot? That’s simple to say, but everyone prefers a different temperature! Scientifically speaking, ambient room temperature is between 20°C/68°F and 26°C/79°F, averaging at about 23°C/73°F. Anything exceeding 27°C /80°F is potentially damaging to your computer. Obviously, this is especially something to watch out for in the summer. The cold is certainly not as hazardous as excessive heat, so temperatures slightly below 20°C/68°F aren’t something to be fearful of.

Temperature and Neodymium Magnets If you start at room temperature (20°C) and get colder, the strength of the magnet increases by a small amount. Below about -125°C, the strength then drops much more quickly. Still, even at temperatures near absolute zero, there is still a good deal of magnetic strength left.

- Room temperature. Colloquially, room temperature is the range of temperatures that people prefer for indoor settings, at which the air feels neither hot nor cold when wearing typical indoor clothing. The range is typically between 15 °C (59 °F) and 18 °C (64 °F) and various methods of climate control are often employed to maintain this thermal comfort level. In certain fields, like science and engineering, and within a particular context, room temperature may have an agreed upon value for temperature.

- By Anne Marie Helmenstine, Ph.D. Definition: Room temperature is a range of temperatures that denote comfortable habitation for humans. There is no 'exact' room temperature. Room temperature can be any temperature between 20 °C and 29 °C. 300 K can also be used as room temperature for easy calculations when using absolute temperature. Related Articles.

- Answer by Nicole Morgan. Confidence votes 65. The element bromine is in the state of a liquid at room temperature (room temperature is roughly 20 degrees Celsius). This is because it's boiling point is 59 degrees Celsius, which is 39 degrees more then room temperature. Actually, Bromine is a Liquid at room temperature it never changes to a gas at room temperature when it is heated up to 300 or so...Kelvin. 1 person found this useful.
