Question

Sam did an experiment with ball bearings in a bottle to show the movement of particles in solids, liquids, and gases. the experimental set-up is shown below: a bottle is shown packed with ball bearings what should sam do to represent the movement of particles in liquids? leave all ball bearings in the bottle, and then shake the bottle slowly while the ball bearings remain in their spot. leave a few ball bearings in the bottle, and then shake the bottle vigorously so that the ball bearings hit one another and the sides of the bottle. remove half of the ball bearings, and then shake the bottle vigorously so the ones at the top hit one another. remove half of the ball bearings, and swirl the bottle so that the ball bearings remain in contact but can move around.

A) Leave all ball bearings in the bottle, and then shake the bottle slowly while the ball bearings remain in their spot.
B) Leave a few ball bearings in the bottle, and then shake the bottle vigorously so that the ball bearings hit one another and the sides of the bottle.
C) Remove half of the ball bearings, and then shake the bottle vigorously so the ones at the top hit one another.
D) Remove half of the ball bearings, and swirl the bottle so that the ball bearings remain in contact but can move around.

Answer 1

To simulate liquid particle movement, Sam should remove half of the ball bearings from the bottle and swirl it, allowing the ball bearings to move around while staying in contact.

Step-by-step explanation:

To represent the movement of particles in liquids using ball bearings in a bottle, Sam should remove half of the ball bearings, and swirl the bottle so that the ball bearings remain in contact but can move around. This simulates the particles in a liquid, which are not as tightly packed as in a solid and are able to move past each other while still being in contact. Other options do not represent the properties of liquid particles as closely as this method does.
