Question

11 water is an example of a molecule with high surface because it has strong intermolecular forces. methane (ch₄) is an example of a molecule with because it has intermolecular forces. as increase, the melting point usually because the molecules

Explanation:

• Surface Tension: Water has strong intermolecular forces (hydrogen bonds), leading to high surface tension. Methane (\(CH_4\)) has weak London dispersion forces (as it is non - polar), so it has low surface tension.
• Melting Point Relationship: As intermolecular forces increase, more energy is required to break the bonds between molecules. So, the melting point usually increases.

Answer:

Water is an example of a molecule with high surface tension because it has strong intermolecular forces. Methane (\(CH_4\)) is an example of a molecule with low surface tension because it has weak intermolecular forces. As intermolecular forces increase, the melting point usually increases because the molecules are held more tightly together.
