Water, Atoms, and Molecules

Emma, Olivia, and Arjun are having a debate about chemistry. They are trying to figure out which of the following can be found on the periodic table of elements. Can you help them?

• Potassium Hydroxide (KOH)

• Water (H2O)

• Carbon (C)

• Hydrochloric Acid (HCl)

Imagine Scarlett, Nora, and Michael are in a science quiz competition. The quizmaster asks, 'Can you tell me the correct equation for calculating the number of neutrons in an atom?' Which option should they choose to win the competition?

• Atomic mass number - Atomic number = Number of Neutrons

• Number of Protons + Atomic mass number = Number of Neutrons

• All of these

• Atomic mass number - Number of Electrons = Number of Protons

Evelyn, Aria, and Emma are having a fun experiment! They mixed sugar and water together to make a yummy solution. Can you guess which one is the solute?

• Water

• Sugar

• Solution

• All of these

Imagine Aria, Benjamin, and Jackson are playing a game of 'Science Charades'. Benjamin is acting out a concept that means to have opposite sides due to different charges. Can you guess what he is trying to portray?

• Cohesion

• Adhesion

• Solvent

• Polarity

• High Specific Heat

Imagine Ava, Olivia, and Abigail are playing with water balloons. They notice that the water inside the balloon is sticking together, forming a shape. This is a result of water molecules feeling this attractive force toward other water molecules. What is this force called?

• Cohesion

• Adhesion

• Solvent

• Polarity

• High Specific Heat

Imagine Samuel, Ethan, and Maya are in a science lab. They are observing a piece of plastic and a piece of glass being dropped into a beaker of water. They notice that the molecules of these substances are attracted to water molecules. What is this phenomenon called?

• Cohesion

• Adhesion

• Solvent

• Polarity

• High Specific Heat

Noah and Benjamin are having a debate. Noah says that the results from the unequal sharing of electrons between hydrogen and oxygen is called 'Cohesion'. Benjamin, however, disagrees and says it's called something else. Nora, who is listening to their debate, thinks it's called 'Polarity'. Who is correct?

• Cohesion

• Adhesion

• Solvent

• Polarity

• High Specific Heat

Imagine Benjamin, Evelyn, and Priya are having a water balloon fight on a hot summer day. Which property of water is helping them maintain their body temperature and thus, homeostasis during this fun activity?

• Cohesion

• Adhesion

• Solvent

• Polarity

• High Specific Heat

Zoe, Maya, and Scarlett were having a fun day at the beach. They decided to conduct a little experiment. When they added salt (NaCI) to their water bottle, it seemed to disappear! Can you guess why this happened? This happens as the polar water molecules break the solid salt into individual chlorine or sodium ions.

• Cohesion

• Adhesion

• Solvent

• Polarity

• High Specific Heat

Imagine Nora, Anika, and Kai are superheroes, each with a unique power related to a property of water. Nora has the power of Cohesion, Anika has the power of Adhesion, and Kai has the power of being a Solvent. But there's a fourth superhero, who has a power that is the reason for all of their powers. Can you guess the property of this fourth superhero?

• Cohesion

• Adhesion

• Solvent

• Polarity

• High Specific Heat
