A Virtual Experiment simulates a series of viscosity experiments.
Viscosity is an important subject in chemistry and chemical engineering.
It is important when dealing with intermolecular forces in liquids and gases and it has enormous relevance in all technological aspects of equipment dealing with liquids or gases. Most university-level chemistry courses include viscosity to some extent. The Ostwald viscometer simulator and the balance simulator allow the student to find out how composition and temperature influence the density and viscosity of an ethanol-water mixture. The falling-ball viscometer simulator allows the student to determine experimentally the size and density of the ball required to measure viscosity of various liquids. Each virtual experiment includes a corresponding theoretical section.
