Two elements are liquid at room temperature (298 K): . . Bromine (Br). ,. . a reddish brown liquid. ,. melts at 265.9 K.. Mercury (Hg). , a toxic metal, melts at 234.32 K.. Four elements melt just a few degrees above room . 2.16. recall the gases present in air and their approximate percentage by volume.  . Air is a mixture of gases . which contains 4/5 nitrogen. 1/5 oxygen. 2.17. describe how experiments involving the reactions of elements such as copper, iron and phosphorus with air can be used to determine the percentage by volume of oxygen in air. The ocean/layer of gas that surrounds the Earth. It is composed of 78% Nitrogen and 21% Oxygen. The other 1 % is a mixture of other gasses. We depend on this balance of gas for our survival. When it is out of balance, we have problems.. The most important among these gases are therefore water vapourand carbon dioxide. The basic principles of the water cycle are well known: Evaporation of liquid water at the surface, condensation, clo and the Impact on Living Things. Earth’s Atmosphere. The gases that surround Earth (and other planets) make up the atmosphere. These gases are like an envelope that protects us from the radiation that is caused by the sun’s . Acknowledgement. G. . .
