#2
Front (Question)
What is surface tension created by?
Back (Answer)
Force between water molecules
#3
Front (Question)
How is surface tension created (long answer, 3 marks or smthng)
Back (Answer)
Each water molecule is pulled equally in all directions by neighbouring molecules which results in a net force or zero. The molecules at the surface don’t have water molecules on all sides so they stick stronger to those next to them which creates a “skin” that behaves like an elastic membrane.
