Explanation:

1. Capillarity is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity. It occurs due to the combined effects of adhesion (attraction between liquid and solid - surface molecules) and cohesion (attraction between liquid - molecules).
2. The smaller the pore size (or particle size in the containers), the greater the capillarity. Container A has the smallest particle - size (0.10 - cm diameter) and shows the highest water - rise (3.6 cm), while container C has the largest particle - size (0.70 - cm diameter) and the lowest water - rise (1.2 cm).
3. There is an inverse relationship between particle size and capillarity. As the particle size decreases, the pore size between particles decreases, and the capillarity increases. This is because smaller pores create stronger adhesive and cohesive forces that pull the liquid up.
4. For the "Pore Space (cm)" graph: Mark the x - axis with containers A, B, and C. On the y - axis, for container A (0.10 - cm diameter), assume a relatively large pore - space value (since it has the highest water - rise, indicating more pore - space for water to rise). For container B (0.40 - cm diameter), mark a lower value, and for container C (0.70 - cm diameter), mark the lowest value.

For the "Time (sec)" graph: Without time data, we can't accurately plot. But if we assume that the time taken for water to rise is related to the capillarity (faster rise in containers with higher capillarity), container A might have the shortest time, container B a medium time, and container C the longest time. Mark the x - axis with containers A, B, C and the y - axis with time values accordingly.
For the "Height (cm)" graph: Mark the x - axis with containers A, B, C. On the y - axis, mark 3.6 cm for container A, 2.4 cm for container B, and 1.2 cm for container C.

Answer:

1. Capillarity is the ability of a liquid to flow in narrow spaces.
2. Capillarity is highest in container A and lowest in container C.
3. There is an inverse relationship: as particle size decreases, capillarity increases.
4. For "Pore Space (cm)" graph: Mark appropriate values on y - axis for A, B, C on x - axis based on water - rise data. For "Time (sec)" graph: Assume relative time values for A, B, C based on capillarity. For "Height (cm)" graph: Mark 3.6 cm for A, 2.4 cm for B, 1.2 cm for C on y - axis with A, B, C on x - axis.
