Viscosity measurements with the falling ball viscometer
Principle: Due to internal friction among their particles, liquids and gases have different viscosities. The viscosity, a function of the substance's structure and its temperature, can be experimentally determined, for example, by measuring the rate of fall of a ball in a tube filled with the liquid to be investigated.
Tasks: Measure the viscosity
1. of methanol-water mixtures of various composition at a constant temperature,
2. of water as a function of the temperature and
3. of methanol as a function of temperature. From the temperature dependence of the viscosity, calculate the energy barriers for the displaceability of water and methanol.
