COMBINED GAS LAW: Set n=50 particles constant and select Hold Constant NOTHING: P¡V1/T1 = P2V2/T2 Note only the particles are constant, so it will not be in the math equation. It is a constant! For the following table, Start with the first data: n=50, T1=300K, V1=5.0nm P1=11.7atm. Use these bold values to calculate the missing data for each new set of conditions in experiment a-d Temperature Volume Pressure 300 5.0 11.7 a) 450 Measured Calculated 11.7 b) Measured Calculated 5.0 2.9 c) 75 10.0 Measured Calculated d) 600 5.0 Measured Calculated Show work for all 4 data points: a) b) c) d)
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.
