Sunita carries out an experiment to investigate diffusion. She uses water and a food dye to find out how the volume of water used affects the time the dye takes to spread evenly through the water. Her prediction is that the more water she uses, the longer the time needed for the dye to spread through it. A) Draw a suitable results table for Sunita
B) Sketch a graph to show what the results will look like if Sunita's prediction is true. Label the axes

Sunita will change the variable water.

Explanation:

Sunita have to change the variable water to perform this experiment of diffusion.This is because she is going to predict that more water she uses longer the time needed for the dye to spread through it.

 As a result she is increasing the amount of water to observe the effect of diffusible substance on diffusion with time.

water   molecules stay close to each other through cohesion, the collective action of hydrogen bonds between water molecules. cohesion plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. this transport occurs even in large trees and against gravity. transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.

water also has high (the attraction of one substance to another) properties because of its polar nature. adhesion of water molecules to plant cell walls counteract gravity while water is transported from roots to leaves.

water exhibits a very high surface tension when compared to other liquids. surface tension is a property of a liquid that holds the surface together and allows it to resist an external force. by capillary action, the water forms concave menisci inside the pores. the high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants.

thus, cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.

therefore, option d) is the correct answer.
