Hi,
I have a question, because I am confused with the definition of surface tension.
In my book it is defined as follows:
"Surface tension is the energy required to increase the surface area of a liquid
by a unit amount"
What do they mean with increasing the surface area, how do you do that? If I take a glass with water it will look like this:
I don't think there is any possible way to increase A. Can someone please help me out?
Thanks in advance!
