Electrons are particles with a negative electric charge. Imagine a system with 10 electrons confined to a volume V. Which of the following processes will increase the potential energy of the system? a. increasing the volume of the container.
b. removing one electron of the system keeping the volume constant.
c. reducing the volume of the container.
d. adding one electron to the system keeping the volume constant.

c. reducing the volume of the container.

d. adding one electron to the system keeping the volume constant.

Explanation:

According to JJ Thomson's Model, He posits that atoms consisted of a positively charged substance distributed uniformly over the entire body of the atom, with negative electrons embedded in this continuous positive charge like seeds in a watermelon. Since electrons repel one another but are, on the other hand, attracted to the center of the positive charge, the potential energy of the system will be based on the volume of such system because the lesser the volume of the system, the less free movement of electron in the system which eventually results into increase in potential energy of the system.

Also, the addition of one electron will cause more repulsions between the electrons, and the more the repulsion, the more increase in the potential energy will occur.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
