Question 307: Properties of Matter

Question

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

Accepted Answer

$$E=2 T\left(4 \pi \mathrm{R}^{2}ight)$$
$$=2(0.03)(4)(3.14)\left(2 	imes 10^{-2}ight)^{2}$$
$$=3.01 	imes 10^{-4} \mathrm{~J}$$

Answer

$$5.06 	imes 10^{-4} \mathrm{~J}$$

Answer

$$3.01 	imes 10^{-4} \mathrm{~J}$$

Answer

$$50.1 	imes 10^{-4} \mathrm{~J}$$

Answer

$$30.16 	imes 10^{-4} \mathrm{~J}$$
