Which statements about surface energy of drops, bubbles and films are correct?

Select all that apply

• Option A

  Coalescence of identical liquid droplets generally releases surface energy.

• Option B

  Breaking one large liquid drop into many smaller drops requires work.

• Option C

  For a soap film, both surfaces must be included while calculating surface energy.

• Option D

  If all surface energy released during coalescence is converted into heat, the liquid temperature can rise.
