Social security and Medicare taxes, also known as FICA taxes must be withheld from your employees' wages. As an employer, you must also pay a matching amount of FICA taxes for your employees. Currently the social security tax rate is 6.2%.ou are also required to pay a matching amount of social security and Medicare taxes for your employees and to pay State and Federal unemployment tax. Have each new employee complete IRS form W-4. You will use this form to calculate the amount of federal income tax to withhold from the employee's wages.
1 The particles of an ideal gas lose no energy to its container. 2  A real gas conducts and radiates heat, thereby losing energy. 3  There is no attraction between the molecules of an ideal gas. 4  A real gas has particle attractions.
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.
