It does not take temperature into consideration. Absolute humidity in the atmosphere ranges from near zero to roughly 30 g (1.1 oz) per cubic metre when the air is saturated at 30 °C (86 °F). [8] [9] Air is a gas, and its volume varies with pressure and temperature, per Boyles law. Absolute humidity is defined as water mass per volume of air ...

Transpiration rates of plants can be measured by a number of techniques, including potometers, lysimeters, porometers, photosynthesis systems and thermometric sap flow sensors. Isotope measurements indicate transpiration is the larger component of evapotranspiration . [ 11 ]

Middle: 1 kg matter, 49 kg water (98% water). If the potatoes are 99% water, the dry mass is 1%. This means that the 100 kg of potatoes contains 1 kg of dry mass, which does not change, as only the water evaporates. In order to make the potatoes be 98% water, the dry mass must become 2% of the total weight—double what it was before.
