Explanation:
Surface tension:
Surface tension is the property of a liquid that allows it to resist an external force due to the cohesive nature of its molecules. It is caused by the imbalance of forces at the surface of a liquid. The molecules at the surface experience a net inward force due to the attractive forces between them, while the molecules in the bulk of the liquid experience forces in all directions due to the surrounding molecules. This results in the formation of a "skin" or surface film that tends to minimize the surface area and create a shape with minimum surface energy.
Effect of temperature on surface tension:
The surface tension of a liquid is affected by various factors, including temperature. As the temperature of a liquid is raised, the kinetic energy of its molecules increases. This increased kinetic energy leads to higher molecular motion and more frequent collisions between molecules.
Effect on intermolecular attraction:
The strength of intermolecular attractions, such as hydrogen bonding or London dispersion forces, determines the surface tension of a liquid. At higher temperatures, the increased kinetic energy of the molecules overcomes the intermolecular attractions to a greater extent. This results in a decrease in the effectiveness of the intermolecular attractions and a reduction in surface tension.
Explanation of the correct option:
Option C, "Increase in temperature increases the kinetic energy of the molecules and effectiveness of intermolecular attraction decreases," is the correct answer.
- Increase in temperature leads to an increase in the kinetic energy of the molecules.
- The increased kinetic energy causes the molecules to move more rapidly and collide more frequently.
- The increased molecular motion and collisions reduce the effectiveness of intermolecular attractions.
- As a result, the surface tension decreases because the intermolecular forces that contribute to surface tension are weakened.
Therefore, as the temperature is raised, the surface tension decreases due to the increased kinetic energy of the molecules and the decreased effectiveness of intermolecular attractions.
