Concept:Viscosity is the internal resistance of a liquid to flow.
Heating a liquid changes this resistance and affects how easily it pours out.
Explanation:When palm oil is cold, it is thick because its viscosity is high.
The layers of the oil resist sliding over one another due to strong intermolecular forces of attraction.
When the oil is heated, its molecules receive more thermal energy and move faster.
This quicker motion weakens the forces between the molecules.
The internal friction in the oil therefore decreases.
A decrease in internal friction means the viscosity of the oil is reduced.
Less viscous oil flows out of the bottle more easily.
Remember that in liquids, viscosity decreases as temperature rises, unlike gases, where viscosity increases.
Answer:B. Viscosity of oil is reduced.
