SUMMARY
The viscosity of glycerol was calculated to be approximately 1.9 P, which is higher than the expected value of 1.5 P. The discussion suggests that evaporated water may contribute to this increased viscosity, as water can absorb into glycerol and enhance its viscosity through hydrogen bonding. The viscosity measurement was conducted at an average temperature of 21 degrees Celsius, with a density of 1200 kg/m³ and a parallax error of 10.7%. The potential for water absorption into glycerol when exposed to air is highlighted as a significant factor affecting viscosity.
