Yes, corn oil is viscous, although it is not as highly viscous as some other substances like honey or motor oil.
While the term "viscous" implies a resistance to flow, all liquids exhibit some degree of viscosity. Corn oil's viscosity can be quantified. For example, its kinematic viscosity is approximately 34.9 mm²/s at 311.15 K (38.00 °C or 100.4 °F). This measurement provides a specific value for how easily corn oil flows under certain conditions. Compared to water, which has a kinematic viscosity of about 1 mm²/s at room temperature, corn oil flows more slowly, indicating higher viscosity. Therefore, while not extremely viscous, corn oil possesses a measurable and significant level of viscosity.
