How high temperature affects osmosis and why?
Osmosis is the passage of moisture through various plant surfaces so a high temperature will increase the speed of osmosis.
What is Electra osmosis?
Osmosis under the influence of an electric field is called Electro-Osmosis. It is the motion of liquid induced by an applied potential across a porous material, capillary tube, membrane, microchannel, or any other fluid conduit. Because electroosmotic velocities are independent of conduit size, as long as the double layer is much smaller than the characteristic length scale of the channel, electroosmotic flow is most significant when in small channels. Electroosmotic flow is an essential component in chemical separation techniques, notably capillary electrophoresis. Electroosmotic flow can occur in natural unfiltered water, as well as buffered solutions.
What effect does temperature increase has on osmosis?
The higher the temperature the faster diffusion occurs which in turn means that the process of osmosis becomes faster as the temperature rises.
Why does the concentration gradient affect osmosis?
Because osmosis is the movement of water molecules from where they are in high concentration to where they are in low concentration.
What is the most important factor in explaining why osmosis occurs spontaneously?
it leads to an increase in entropy
What will happen to the water in the capillary tube during the investigation of osmosis?
It will increase due to osmosis
How fluids move across capillary membranes?
Osmosis.
What is water forced through capillary walls by?
Osmosis
Which process describes the pushing of water across the capillary (blood vessel) membrane?
Osmosis
What are the two water properties used to move water upward in plants?
osmosis and capillary action
What is the process when the root absorbs water takes it up to the plant?
Capillary Action.add. The water will usually cross the root membrane because of osmosis due to dissolved salts.At the other end of the plant, the Stomata are allowing the exchange of CO2 and O2, and also allow the water to evaporate from the plant.In between the capillary action moves the water, driven by the Osmosis, and the Evaporation.
What is the process in which water is evaporated from trees?
Osmosis through the roots, then capillary action up the trunk and branches.
Would there be an increase or decrease in the rate of osmosis if the temperature were raised?
Osmosis is a physical process in which the net flow of solvent is from there higher concentration to their lower concentration. As osmosis is physical process it first increase with increase in temprature but get constant after some extent.
What 2 parameters are responsible for creating the movement filtration and reabsorption of fluid across the capillary wall?
membranes and osmosis pressures
Would there be an increase or a decrease in the rate of osmosis if WE raised the temperature?
There would be an increase
What are the disadvantage of a plant cell model?
if you fill it up too much the pressure will be so high it stops osmosis therefore affcets your results if you were investigation osmosis
What is the pulling of water up a tube to tansport the water from the roots to the shoots of the plants?
my f...ed up head and the website dont now so f... this f...ed website i totaly get you these dick heads dont know nun
