You have three capillary tubes that are made of paraffin wax and have diameters of \(1.00 \mathrm{~mm}, 2. 00 \mathrm{~mm}\), and \(3.00 \mathrm{~mm}\).

(a) Is the meniscus that water forms in each tube convex or concave?

(b) How might you change the water so that the answer to part \(a\) changes?

(c) Because any liquid surface in a capillary tube curves either concavely or convexly, the peak or trough of the meniscus is vertically higher or lower than the location where the liquid surface meets the tube wall. Which of the three capillary tubes has the greatest vertical separation distance between the liquid-wall contact point and the meniscus peak or trough?
