3. Juan observed the ice as it melts on the table. He wondered what happened to the movement of the particles present on the ice. Which of the following concepts can help Juan?

• a. The movement of the particles become slower as phase change happens.
• b. The movement of the particles become slower because there are spaces between particles.
• c. The movement of the particles become faster because the temperature of the ice changes sufficiently as phase change happens.
• d. The movement of the particles become faster because the particles in ice is faster than the particles in water.

4. Which of the following statements correctly explains the difference between intramolecular and intermolecular forces of attraction?

• a. Intramolecular forces occur between molecules, while intermolecular forces occur within a molecule.
• b. Intramolecular forces hold atoms together within a molecule, while intermolecular forces occur between different molecules.
• c. Intermolecular forces are stronger than intramolecular forces because they involve the sharing of electrons.
• d. Intramolecular forces are responsible for physical properties like boiling points, while intermolecular forces are responsible for chemical bonds.

• c. Liquids have a definite volume but take the shape of the container.
• d. Liquids have neither a fixed shape nor a fixed volume

7. Which of the following best describes surface tension in liquids?

• a. It is the resistance of liquid to flow.
• b. It is the tendency of the liquid to spread out over a surface.
• c. It is the force that causes the liquid to form drops.
