Question

A soap bubble of radius alpha has been formed at normal temperature and pressure under isothermal process. Compute the work done. The surface tension of soap solution is sigma

Answer 1

Explanation:

Hey Buddy here's ur answer

Answer 2

The surface tension of the soap solution is W = T(8πR^2)

Explanation:

As we know that:

Total Work done "W" = T(ΔA)

ΔA = (4πR^2)

Also, the soap bubbles has two surfaces

So when we calculate the total work done, we include both sides

Total work done = W = T(8πR^2)

So, the surface tension will be equal to W = T(8πR^2)
