| 21. | At higher-than-standard elevation ( sea level ) and higher-than-standard temperature, air density is lower than standard density.
|
| 22. | A variation in standard temperature can result in a significant volumetric variation for the same mass flow rate.
|
| 23. | He also devised a special " physiological thermometer " in which zero was the standard temperature of health.
|
| 24. | The volume of the gas is calculated as if measured at standard temperature and pressure ( STP ).
|
| 25. | Assuming a reference temperature of 0�F, the following formula may be used under standard temperature ranges and pressure:
|
| 26. | It has the chemical formula Si 3 H 8, and is a liquid at standard temperature and pressure.
|
| 27. | Textile measurements are taken at a standard temperature and humidity, because fibers can absorb moisture from the air.
|
| 28. | At normal conditions such as standard temperature and pressure, most real gases behave qualitatively like an ideal gas.
|
| 29. | They have very similar properties : they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure.
|
| 30. | One cubic meter of air at 20 �C has a mass of 1.204 kg at standard temperature and pressure.
