Two mercury droplets radii 0.1 cm and 0.2 cm collapse into one single drop. What amount of energy is released/absorbed? The sur4face tension of mercury `T=435.5xx10^(-3)Nm^(-1)`

A

`32.23xx10^(-7)` (Released)

B

`32.23xx10^(-7)` (Absorbed)

C

`64.46xx10^(-7)` (Absorbed)

D

`64.46xx10^(-7)` (released)

Text Solution

Verified by Experts

The correct Answer is:
B
`V=V_(1)+V_(2)impliesR^(3)=r_(1)^(3)+r_(2)^(3)`
`E=TxxDeltaA`
