This activity illustrates the effect of intermolecular forces on surface tension of a liquid. Students attempt to place drops of various types of liquids on the face of a penny (or any available coin). The substances with stronger intermolecular forces have greater surface tensions and hence it is possible to place more drops on the face of the penny.
This demonstration/activity introduces students to the concept of limiting reagent in a chemical reaction. Too often, students think that one can produce more product by using larger quantities of... read more
