Answer the following 1) A sample of argon gas occupies a volume of 1.20 L at 125 Celsius. Using Charles's Law determine the temperature, in Celsius, at which the volume of the gas is 1.00 L at the same pressure and number of moles? 2) A sample of carbon monoxide (CO) gas has a volume of 7.31 L at a pressure of 735 mmHg and a temperature of 45.0 Celsius. Using the combined gas law, determine the temperature in Celsius if the pressure is changed to 1275 mmHg and the volume is changed to 0.800 L and the number of moles remain the same. 3) Using the ideal gas law, calculate the number of moles of gas if the temperature is -173 Celsius, the volume is 2.50 L, and the pressure is 2.50 atm?
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.
