Your careless, clumsy lab mate has accidentally allowed carbon monoxide to leak out of a reactor, causing your lab’s CO monitor alarm to sound. After you quickly put on the appropriate Personal Protective Equipment, you find the leak and seal it. Then, you close your lab door, shut the windows, and call OSHA to report the hazard. When OSHA technicians arrive, they begin ventilating the 3000-ft3 laboratory by pumping 25 ft3/min of fresh air into the room and removing the contaminated air at the same rate. They put a shop fan in the laboratory, such that the air is well-mixed. They also install a digital CO composition monitor, which currently reads 2 mol%. OSHA tells you that the laboratory is safe when there is less than 35 ppm of CO in the lab. How long must you wait to get back to work?
Ideal and Real Gases
Ideal gases obey conditions of the general gas laws under all states of pressure and temperature. Ideal gases are also named perfect gases. The attributes of ideal gases are as follows,
Gas Laws
Gas laws describe the ways in which volume, temperature, pressure, and other conditions correlate when matter is in a gaseous state. The very first observations about the physical properties of gases was made by Robert Boyle in 1662. Later discoveries were made by Charles, Gay-Lussac, Avogadro, and others. Eventually, these observations were combined to produce the ideal gas law.
Gaseous State
It is well known that matter exists in different forms in our surroundings. There are five known states of matter, such as solids, gases, liquids, plasma and Bose-Einstein condensate. The last two are known newly in the recent days. Thus, the detailed forms of matter studied are solids, gases and liquids. The best example of a substance that is present in different states is water. It is solid ice, gaseous vapor or steam and liquid water depending on the temperature and pressure conditions. This is due to the difference in the intermolecular forces and distances. The occurrence of three different phases is due to the difference in the two major forces, the force which tends to tightly hold molecules i.e., forces of attraction and the disruptive forces obtained from the thermal energy of molecules.
