Air is made of atoms belonging to several elements that are gaseous at room temperature. As gases, these elements are spaced apart with a low density, which is why we can walk through the air easily. However, the atoms still have mass and thus the Earth's gravity pulls them downward. ...
Question: What is berkelium's boiling point? Boiling Point: The boiling point of a substance is the temperature where it changes to a gaseous form. While some elements have a high boiling point, the elements that are gaseous at room temperature, such as oxygen, have an extremely low boiling...
Metals are those elements that reflect light and hence possess lustre. Moreover, they are good conductors of heat and electricity, malleable (i.e., hammered to form sheets) and ductile (i.e., can be drawn into wires), exist as solids at room temperature (except mercury) and possess high...
Similarly, hydrogen and oxygen, which are both gaseous elements can combine to form water, which is a liquid compound, not a gas, at room temperature. The process by which such combinations and transformations of elements into compounds take place is called achemical reaction. ...
At room temperature, injected charge leaks away over a few minutes to a few hours for commercial acrylic. Chilling acrylic significantly reduces the speed that free charges can move inside the acrylic, and this dramatically increases the time that trapped charges can be stored. At dry ice ...
Unlike E85 and M85 which are both liquid fuels, propane (also known as Liquefied Petroleum Gas, LP-Gas or LPG), and natural gas are both gaseous fuels. That means they are a vapor at room temperature and must be contained in a special high pressure fuel cylinder. Natural gas can be use...
Fortunately, the chemical reaction between oxygen and lubricant molecules at room temperature is slow and oxidative degradation is not an issue under these conditions. The situation changes when reaction conditions are altered to favor a more rapid reaction rate. ...
What is the name of the fat which remains solid at room temperature?Most of the known elements are (at room temperature and pressure): \\ A. solid and metallic B. sold and non-metallic C. gaseous and non-metallic D. liquid and metallicWhat is the typical state of nonmetals at ...
Which elements are gases at STP? What substance has the highest density at room temperature? What is the charge of nitrogen gas? What is the physical state of helium at room temperature? Name two major constituent gases of atmosphere
