art II. Complete each statement below by filling in the blanks with the correct words found from the puzzle. Gases, like any other states of matter, consist of very tiny particles, each of which has mass that are very far from each other. Thus, making gases high ompressible and have low density. Gas particles move rapidly in straight lines, travel constantly in random rections. Gases diffuse rapidly that allows two or more gases to mix readily when ombined. Because of the wide spaces between gas particles, the forces of traction between them are The is conserved in elastic collision of gas particles. Thus, articles of gases that collide each other or with the walls of its container do not se kinetic energy, instead, it is only transferred to the lower-energy particle and ontinue to move. The average energy of gas particles is directly proportional to e absolute temperature of the gas
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.
