Physics · Properties of Liquids
The surface tensions of two liquids having the same density, T1 and T2, are measured using the capillary rise method. Two tubes with inner radii of r1 and r2 are used, where r1 > r2. If the measured liquid heights in these tubes are h1 and h2 respectively, and it is found that T1 = T2, then which of the following relations is correct? (Ignore the weight of the liquid above the lowest point of the meniscus.)
- 1h1 < h2 and T1 = T2✓
- 2h1 = h2 and T1 = T2
- 3h1 > h2 and T1 = T2
- 4h1 > h2 and T1 < T2
Correct answer
h1 < h2 and T1 = T2
