Molecular formula : MW : CAS :
nature : put mercury thermometer with the mercury wet gauze-wrapped one end of gauze soaked in water to maintain adequate wetting gauze. The wet gauze to keep moisture evaporation when the air needs to absorb heat, heat spread through the air from mercury-added. Therefore, the mercury-air temperature than the low temperature, that is no more than a pack of wet gauze before low. This time measured the temperature known as wet-bulb temperature. As measured by the air temperature and the wet bulb temperature, we can calculate the air contained in the steam volume.
