The work done in blowing a soap bubble of surface tension 0.06 N m⁻¹ from 2 cm radius to 5 cm radius is

Surface tension of mercury is 0.465 N m⁻¹. The excess pressure inside a mercury drop of diameter 6 mm is

The surface tension of soap solution at a temperature 20°C is 2.5 × 10⁻² N m⁻¹. The excess pressure inside a bubble of soap solution of radius 6 mm is

In previous question, if an air bubble of the same dimensions were formed at a depth of 30 cm inside a container containing the soap solution of relative density 1.20, then the pressure inside the bubble is (Take 1 atm = 1.01 × 10⁵ Pa)

A capillary tube (I) is dipped in water. Another identical tube (II) is dipped in a soap-water solution. Which of the following shows the relative nature of the liquid columns in the two tubes?

A capillary tube of radius r is immersed in water and water rises in it to a height h. The mass of water in the capillary tube is 5 g. Another capillary tube of radius 2r is immersed in water. The mass of water that will rise in this tube is

If the surface tension of water is 0.06 N m⁻¹, then the capillary rise in a tube of a diameter 1 mm is
