Now you have the ideal gas law rewritten in a form you can use with the information you were given. La ley de los gases se expresa matemáticamente con la fórmula: PV =nRT. The ideal gas equation is a summary of the Gas Laws (Boyle's Law, Charles' Law, and Avogadro's Law) and real gases obey the gas equation reasonably well at lower pressures and higher temperatures. PV = NkT. This law can be derived from the kinetic theory of gases and relies on the assumptions that (1) the gas consists of a large number of molecules, which are in random motion and obey Newton's laws of motion, (2) the volume of the molecules is negligibly small compared with the volume The specific heat (= specific heat capacity) at constant pressure and constant volume processes, and the ratio of specific heats and individual gas constants - R - for some commonly used "ideal gases", are in the table below (approximate values at 68 o F (20 o C) and 14.314 J/(mol·K) = 0.
