The amount of energy required to form a soap bubble of radius $2 cm$ from a soap solution is nearly: (surface tension of soap solution = $0.03 N m^{- 1}$ )NEET 2023 (All India)

Options:

Answer:

Solution:

Soap bubble has two free surface.
Therefore, amount of energy required $= 2 [S \times A] = 2 [0.03 \times (4 π {(2 \times 10^{- 2})}^{2})] = 3.01 \times 10^{- 4} J$
