Localized adiposity. 1  ICD-9-CM 278.1 is a billable medical code that can be used to indicate a diagnosis on a reimbursement claim, however, 278.1 should only be used for claims with a date of service on or before September 30, 2015. For claims with a date of service on or after October 1, 2015, use an equivalent ICD-10-CM code (or codes).
One mole of an ideal gas has a volume of 22.7 L at STP as defined by IUPAC. At normal conditions such as standard temperature and pressure, most real gases behave qualitatively like an ideal gas. Many gases such as nitrogen, oxygen, hydrogen, noble gases, and some heavier gases like carbon dioxide can be treated like ideal gases within reasonable tolerances.
10.9 Real Gases: Deviations from Ideal Behavior. Although the ideal-gas equation is a very useful description of gases, all real gases fail to obey the relationship to some degree. For a mole of ideal gas (n = 1) the quantity PV/RT equals 1 at all pressures. In Figure 10.20, PV/RT is plotted as a function of P for 1 mol of several different gases. At high pressures the deviation from ideal behavior (PV/RT = 1) is large and is different for each gas.
