Question

fall final exam (2025 - m)
possible points: 4.11
match the term to the correct description
sticky force of molecule to form a surface
when molecules of the same substance stick together
when molecules of different substances stick together
adhesion cohesion surface tension

Explanation:

Step1: Analyze "Sticky force of molecule to form a surface"

Surface tension is the cohesive force between liquid molecules that creates a 'sticky' surface (like water beading). So this matches "surface tension".

Step2: Analyze "When molecules of the same substance stick together"

Cohesion is the attraction between molecules of the same substance (e.g., water molecules sticking to each other). So this matches "cohesion".

Step3: Analyze "When molecules of different substances stick together"

Adhesion is the attraction between molecules of different substances (e.g., water sticking to glass). So this matches "adhesion".

Answer:

• "Sticky force of molecule to form a surface" → surface tension
• "When molecules of the same substance stick together" → cohesion
• "When molecules of different substances stick together" → adhesion
