You stir a cup of hot chocolate with a spoon. why does the spoon keep its shape in the drink? select one: a. the spoon's particles do not move as much as the hot chocolate's particles which move in all directions. b. the spoon's particles move close to one another while the hot chocolate's particles move randomly in different directions. c. the spoon's particles do not move while the hot chocolate's particles move close to one another. d. the spoon's particles move in all directions while the hot chocolate's particles move close together

Option (c) is the correct answer.

Explanation:

As we know that spoon is a solid substance and in solids particles are held by strong intermolecular forces of attraction.

As a result, these particles only vibrate at their mean position but they do not move or collide with each other.

On the other hand, particles of hot chocolate will have high kinetic energy due to which they will move rapidly and collide with each other.

So, when we stir a spoon in a cup of hot chocolate then heat energy from the hot chocolate will be released into the surroundings. This will make the particles of hot chocolate to come closer to each other.

Thus, we can conclude that the spoon keep its shape in the drink because the spoon's particles do not move while the hot chocolate's particles move close to one another.
