Answer:
38.
Explanation:
All water that are present in soil is not available for the plants. Gravitation water is present in soil due to the gravitational force. The gravitation water remains for short time and cannot be consumed by the plants.
The capillary water is available to the plants and this water is attained in the soil pores. The total water present in soil sample is 100 ml. 62ml is gravitation water. The volume of capillary water = total water - gravitation water = 100 - 62 = 38ml.
Thus, the answer is 38ml.
The purple color of potassium permanganate gradually spreads throughout the water in the jar by the process of diffusion.
- Diffusion is the process of movement of a substance from the region of higher concentration to the regions of lower concentration. Diffusion occurs in liquids as well as gases.
- Potassium permanganate is a purple color compound, when it is added in a jar of water it spreads throughout the water by the virtue of diffusion.
- The concentration of potassium permanganate is higher at one point and the other regions in the jar have its nil or low concentrations initially, this leads to the set up of a concentration gradient.
- As time passes diffusion occurs and the particles of potassium permanganate keep on migrating to the regions of low concentration until the concentration is uniform throughout the jar. Ultimately, it spread throughout the jar making the water purple.
