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.

QUESTION A: When John had an asthma attack, he was given oxygen through a face mask. The gauge on the 12-L tank of compressed oxygen reads 3800 mm Hg. How many liters would this same gas occupy at a final pressure of 570 mm Hg when temperature and amount of gas does not change?
B. In an underground gas reserve, a bubble of methane gas has a volume of 45.0 mL at 1.60 atm pressure. What volume in liters (L) will the gas bubble occupy when it reaches the surface where the atmospheric pressure is 744 mm Hg, and assuming there is no change in the temperature and amount of gas?
C. A gas sample has a temperature of 22 ˚C with an unknown volume. The same gas has a volume of 456 mL when the temperature is 86 ˚C, with no change in the pressure or amount of gas. What was the initial volume, in liters (L) of the gas?
