a) How can the surface tension of water be broken? Float something on the surface of water. How can you break the surface tension without touching the surface with your finger?
b) Heat and cool a sample of honey. Compare the viscosities of each. Find another liquid to experiment with. Report your results below and explain your observations in terms of intermolecular forces.
the surface tension of water is broken by adding detergents and soaps
we know that
the surface tension of water decreased with increasing temperature
heating the water will break the surface tension
and it will be difficult for the object to float
when honey is heated
the heating will give energy to the atoms
this energy is enough to overcome the intemolecular forces that binds the atoms together
the atoms in the honey can flow easily
as a result
the viscosity will decrease upon heating
the viscosity will increase upon cooling
this experiment can also be done using a sugar syrup
