Kinetic-Theory of Gases

Kinetic theory of gases is the model or method which was developed in the 19th century by Maxwell and Boltzmann. This is possible as the interatomic force which is of short-range forces that are important for solids and liquids can be neglected for gases. This theory or gas law gives a molecular interpretation of the pressure and temperature of a gas and is consistent with gas laws and Avogadro’s hypothesis. This theory is very helpful to correctly explain the specific heat capacities of many gases, kinetic energy and it also explains the transport qualities such as viscosity, thermal conductivity, and diffusion with molecular parameters. As stated in the kinetic-molecular theory, the temperature of a substance or gas particle is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles, called average kinetic energy.

The label has come off a cylinder of gas in your laboratory. You know only that one species of gas is contained in the cylinder, but you do not know whether it is hydrogen, oxygen, or nitrogen. To find out, you evacuate a 5-liter flask, seal it and weigh it, then let gas from the cylinder flow into it until the gauge pressure equals 1.00 atm. The flask is reweighed, and the mass of the added gas is found to be 13.0 g. Room temperature is 27°C, and barometric pressure is 1.00 atm. What is the gas?

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-ft3laboratory 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?
