Solidarity, Adhesion, Cohesion
Learning Time: 2-8 hours
Content: Solidarity, adhesion, and cohesion are concepts that examine the molecular forces between substances. This subject covers the explanation of cohesion (attraction between the same substances), adhesion (attraction between different substances), and phenomena such as surface tension and capillarity. Surface tension and capillarity are emphasized in TYT, while practical applications of these forces are emphasized in AYT. The current 2025 curriculum also covers their roles in biological systems (plant capillarity) and their applications in engineering (capillary technologies). Learning this subject forms the basis for fluid behavior and practical applications.
