The surface tension of soap solution is

0.03\mathrm{N}{\mathrm{m}^{ - 1}}

. the work done in blowing to from a soap bubble of surface area

40\mathrm{c}{\mathrm{m}^2},\left( {\mathrm{in J}} \right),\mathrm{is}

View answer and explanation

Correct option: B

2.4 \times {10^{ - 4}}

Option B (

2.4 \times {10^{ - 4}}

) is correct because the work done in forming a soap bubble is calculated using the formula

W = T \times 2 \times \Delta A

.
