Question 1 Report
Which of the following substances is most viscous at room temperature?
Answer Details
Out of the given options, palm oil is the most viscous at room temperature. Viscosity is a measure of a fluid's resistance to flow, and is affected by factors such as temperature and molecular structure of the fluid. Palm oil has a higher molecular weight and longer hydrocarbon chains compared to the other options, which leads to stronger intermolecular forces and greater resistance to flow. This makes it more viscous than water, alcohol, petrol, and kerosene at room temperature.
