Palm oil from a bottle flows out more easily after it has been heated because the
A.
Molecules do not increase speed during the heating
B.
Viscosity of oil is reduced
C.
Oil molecules force each other out
D.
Adhesion between the oil molecules and those of the bottle is increased
Correct Answer: Option 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.
