Hexane (/ ˈ h ɛ k s eɪ n /) or n-hexane is an organic compound, a straight-chain alkane with six carbon atoms and the molecular formula C 6 H 14. [ 7 ] Hexane is a colorless liquid, odorless when pure, and with a boiling point of approximately 69 °C (156 °F).

The dynamic viscosity of water is about 0.89 mPa·s at room temperature (25 °C). As a function of temperature in kelvins, the viscosity can be estimated using the semi-empirical Vogel-Fulcher-Tammann equation: = where A = 0.02939 mPa·s, B = 507.88 K, and C = 149.3 K. [88] Experimentally determined values of the viscosity are also given in ...
A brief review of the techniques available for measuring the volume viscosity of liquids can be found in Dukhin & Goetz [10] and Sharma (2019). [15] One such method is by using an acoustic rheometer. Below are values of the volume viscosity for several Newtonian liquids at 25 °C (reported in cP): [16]

Increasing temperature results in a decrease in viscosity because a larger temperature means particles have greater thermal energy and are more easily able to overcome the attractive forces binding them together. An everyday example of this viscosity decrease is cooking oil moving more fluidly in a hot frying pan than in a cold one.
