Study Notes
Measuring Absorbed Water Volume
- A device called a potometer is used to measure the volume of water absorbed.
- A capillary tube is used, modeled as a cylinder.
- The radius (r) of the tube is 2 x 1 mm.
- The volume (V) of absorbed water is calculated using the equation: V = πr²h, where h is the height of absorbed water.
- V = πr²(h₁ - h₀) , where h₁ is the final height and h₀ is the initial height.
