Technical data

Density of liquids

Item No. P2140100

Principle

The density of water and glycerol is determined as a function of temperature using the Mohr balance.

Benefits

  • Mohr density balance enables high-precision measurements
  • Interdisciplinary use also in applied sciences or physical chemistry

Tasks

The density of water and glycerol is measured in 1 to 2 °C steps over a temperature range from 0 to 20 °C, then in larger steps up to 50 °C.

Learning objectives

  • Hydrogen bond
  • Water anomaly
  • Volume expansion
  • Melting
  • Evaporation
  • Mohr balance
