HELP ME PL Which statement describes why the viscosity of olive oil is higher than that of
rubbing alcohol?
A. The molecules that make up olive oil are longer than those that
make up alcohol, so they have more resistance to sliding past one
another.
B. The molecules that make up olive oil repel one another, while the
molecules that make up alcohol are attracted to one another.
C. The molecules that make up olive oil are shorter than those that
make up alcohol, so they have more resistance to sliding past one
another.
D. The molecules that make up olive oil are attracted to one another,
while the molecules that make up alcohol repel one another.
