The correct answer is B. friction between oil layers is reduced.
This is because:
* When you heat something, like palm oil, you're giving the molecules inside it more energy.
* This extra energy makes the molecules move around faster and more freely.
* Palm oil, like any liquid, has layers of molecules that slide past each other.
* Friction is the force that resists this sliding.
* When the oil is cold, the molecules move slowly, and there's more friction between the layers, making it thick and hard to pour.
* When you heat the oil, the molecules move faster, reducing the friction between the layers. This makes the oil thinner and easier to pour.
* Why the other options are wrong:
* A. molecules are given potential energy during the heating: While heating does increase the kinetic energy (motion energy) of the molecules, it does not primarily increase potential energy in a way that causes easier flow.
* C. oil molecules force each other out: While the increased motion of the molecules does cause them to spread out slightly, it is not the main reason the oil flows easier.
* D. adhesion between the oil molecules and those of the bottle is increased: Adhesion is the sticking of different substances together. While there is adhesion, heating does not increase the adhesion enough to cause a noticeable flow change.
