When water potential in the blood decreases, the body may release antidiuretic hormone (ADH) to retain more water and decrease urine production. This helps to maintain blood volume and pressure. However, if water potential continues to decrease, it can lead to dehydration and an imbalance in electrolyte levels.
As water is pulled downhill by gravity, its potential energy decreases and kinetic energy increases. The potential energy is converted into kinetic energy as the water gains speed and momentum while flowing downhill.
Pressure and solute concentration are the two physical factors that affect water potential. Pressure increases water potential, while solute concentration decreases water potential.
In shallow water, the wavelength of the wave decreases while the wave height increases. This happens because the wave speed decreases as it interacts with the seafloor, causing the wave to become steeper and taller.
Actually it's not weight we are dealing with here, it is actually density. So what happens is when temperature increases, the density decreases and volume increases or vice versa if the temperature decreases, the density increases and the volume decreases.
Take for example a dam, and the process which electricity is produced from water by gravitational force. When water rushes down the penstock into the turbine, it creates a rotational energy. The rotational energy is transfered to the spindle. At which point the spindle passes its energy off to an alternator. The alternator will create electricity. Thus, when you take gravity into account, water is a great potential energy. You need little to no fossil fuels to sometimes create more energy than a power plant. Simple and sweet too, I might have missed a couple key concepts
Water with dissolved carbon dioxide is acidic.
The water potential decreases when you dissolve sugar in water because the addition of solute particles reduces the availability of free water molecules. This decrease in water potential is due to the lowering of the chemical potential of water as it becomes less likely to move from an area of higher water potential to an area of lower water potential.

.The pressure of the water decreases.
Pressure and solute concentration are the two physical factors that affect water potential. Pressure increases water potential, while solute concentration decreases water potential.
temperature decreases
they absorb water through the permeable membrane and on ovr absorbing...they burst up
In every liquid (with the exception of water) the molecules, when the temperature decreases, contract.
ADH
decreases it - no water then no water potential.
The water potential is really just the sum of the pressure potential and the solute potential. Obviously, then, lower pressure potential would lower the water potential, and so would lower solute potential. To lower the solute potential, the moles of the solute would actually have to increase. This probably seems backwards, but the equation for solute potential is -iCRT (where C is moles/liter, for some reason). Because there's a negative sign, the more moles you have, the less the solute potential is. Hopefully that helps.
Distilled water would have a higher water potential than a red blood cell because the formula for obtaining water potential is -iCRT, where i=ionization constant, C=molar concentration, R=pressure constant--usually 0.0831 liter bars/mole K, and T=temperature in Kelvins. Since distilled has a molar concentration of 0, the water potential would be 0. And a red blood cell would have a negative water potential because it does have some sort of molar concentration. Thus, distilled water would have a higher water potential because 0 is greater than a negative number. As a note, water always flows from areas of higher water potential to areas of lower water potential. Therefore, it is easy to imagine that water flows toward more concentrated solutions, meaning it would flow to the red blood cell. If distilled water flows to the red blood cell, then it must have a higher water potential than the red blood cell.
