Molecular formula : MW : CAS :
nature : obey Newton's law of friction of the fluid. General viscous smaller, and with the temperature change. When the temperature rises, reducing the viscosity of liquid and gas increased. For example, at 20 ° C, water is the viscosity of a coin Pago seconds, glycerol 830 cents Pago seconds, the air 0.018 cents Pago seconds, in 30 ° C, water is 0.8 cents Pago seconds, glycerol is 630 cents Pago seconds, the air is 0.019 cents Pago seconds.
