Palm oil from a bottle flows out more easily after it has been heated because the
- Molecules do not increase speed during the heating
-
Viscosity of oil is reduced
- Oil molecules force each other out
- Adhesion between the oil molecules and those of the bottle is increased
The correct answer is: B
Explanation
If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid.The result is that liquids show a reduction in viscosity with increasing temperature. With high temperatures, viscosity increases in gases and decreases in liquids, the drag force will do the same.
