A gaseous system A, with an initial temperature T1, is set to interact with a gaseous system B at an initial temperature T2. The molecules of A and B, both monoatomic, can interact with each other through a wall without mixing. It is known that T2 > T1. Considering this situation, answer the following question. Consider the statements below and type the sum of the numbers associated with the correct ones (write only the number): (1) System B necessarily has a higher initial energy than A (2) System A may have a higher initial energy than B (4) the molecules of system B have a greater average kinetic energy than those of system A (8) From a microscopic point of view, there can never be a collision between molecules in which a molecule of system A loses energy to a molecule of system B (16) The system with more molecules necessarily has the lowest energy
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.
