Assume the question is for measuring water content in plant
Measuring dry weight assume there is no organic compound (the plant constituent) vaporized in the process of drying. In other word, it assume neither the plant constituent is volatile nor thermally break down to volatile compound under process of drying.
Plant mostly comprised of long chain hydrocarbon such as cellulose or protein and unlikely to be destruct under low temperature drying.

What is water potential measured in?
its always measured in Psi(Ψ)
What is water vapor in the air measured with?
measured as humidity in the air with a hygrometer.
A student measured the volume of water in a pan The student boiled the water for thirty minutes and then measured the volume of the water again The volume of water most likely be what?
Less, possibly gone.
Distance is measured in miles Time is measured in minutes and hours Wheat is measured in bushels What is measured in acre-feet?
Water deposited by rain or artificial irrigation.
Is being composed of hydrogen and oxygen a physical property of water?
Yes, being composed of hydrogen and oxygen is a physical property of water. Physical properties refer to characteristics that can be observed or measured without changing the composition or identity of a substance, and the specific arrangement of hydrogen and oxygen atoms in water molecules is a defining physical property of water.
When humidity is being measured what is actually being measured?
Humidity is the concentration of water molecules existing as vapor. The actual measurement is "relative humidity" because it does not determine the volume directly, only the ratio of the volume compared to the maximum the air can hold at that temperature. This dtermines the amount of condensation that can occur if the air is cooled.
What instrument measures pressure within a water system?
It's usually just called a "pressure gauge", the assumption being that you know, or a label on it tells you, that it is measuring water-pressure.
How is water utility service to your home measured?
The water you use is measured by the number of gallons you use.
What was Dalton's assumption about the composition of water?
Dalton supposed that the chemical formula of water is OH.
What is water potential measured in?
its always measured in Psi(Ψ)
What is the unit used for measuring the calorific value?
Calories are measured in Kilocalories (kcal) which is 1000 calories they food or whatever is being measured is measured in Calories... THey measure calories by seeing how much water they can evaporate by burning the organic element which is calculated into joules and then into calories...
What is water vapor in the air measured with?
measured as humidity in the air with a hygrometer.
How is water measured?
something
How many gallons of water are in a pool 16 x 26 that is 4 feet deep?
The question can only be answered if you make some assumption about the units in which the length and width are measured. Although there is no justification for doing so, IF you assume they are feet, then the answer is 12,448 US gallons.
Why water is not measured in kg?
because water is a liquid.
What is displacement measured in?
Displacement can be measured in any unit that measures distance but the SI unit is meters. When talking about the displacement of a ship, it refers to the mass of water that the ship displaces. This is actually equal to the weight of the ship and is usually expressed in metric tons.
Is the weight and volume of water butter eggs and milk the same?
The weight of eggs, water and milk are measured in ounces or cups. The volume of water, eggs, and milk is measured as a liquid. The volume of butter is measured as a solid.
