| Abstract: | In the experiment of measuring the air density and the universal gas constant,organic glass density bottle was adopted instead of glass density bottle,and the high accuracy pointer-type vacuum meter was used instead of thermocouple vacuum gauge.The air pressure was changed by the leakage between the rubber hose and density bottle connector,and the mass of the gas was measured by the electronic physical balance.The improved device was well for student experiment. |
| Keywords: | air density gas universal constant ideal gas equation |
