What is the pressure inside a vapour bubble of radius

10^{-3} \mathrm{~m}

formed in boiling water? Surface tension of water at 100 is

0.059 \mathrm{~Nm}^{-1}

and

1 \mathrm{~atm}=101325 \mathrm{~Nm}^{-2}

.

View answer and explanation

Correct option: A

101443 \mathrm{~Nm}^{-2}

Option A (

101443 \mathrm{~Nm}^{-2}

) is correct because the pressure inside the vapor bubble is the sum of the atmospheric pressure and the excess pressure due to surface tension.
