To assist in comparing different gases and in measuring changes of gases it is necessary to have a standard or constant to measure these changes against. The standard used for gases are: a pressure of 760 millimeters of mercury (1,013.25 mb) and a temperature of 0C. These figures are sometimes referred to as Standard Temperature and Pressure (STP).Learning Objective: Recognize how pressure, temperature, and density affect the atmosphere and describe how the gas laws are applied in meteorology. |
