Two mercury droplets of radii 0.1 cm and 0.2 cm collapse into one single drop. What amount of energy is released? The surface tension of mercury `T = 435. 5xx10^(-3) Nm^(-1)`

Text Solution

AI Generated Solution

To find the amount of energy released when two mercury droplets of radii 0.1 cm and 0.2 cm collapse into a single drop, we can follow these steps: ### Step 1: Understand the Concept of Surface Energy The surface energy (or surface tension energy) of a droplet is given by the formula: \[ Q = T \times A \] where \( T \) is the surface tension and \( A \) is the surface area of the droplet. ### Step 2: Calculate the Surface Energy of Individual Droplets ...
