Sticky Molecules Quiz

What is adhesion of sticky molecules?

• Inability of molecules to stick to other surfaces or substances

• Ability of molecules to stick to other surfaces or substances

• The process of molecules repelling each other

• The ability of molecules to change shape and size

Explain cohesion of sticky molecules.

• Attraction between molecules of the same substance

• Attraction between molecules of different substances

• Absence of any interaction between molecules

• Repulsion between molecules of different substances

What are the properties of adhesive molecules?

• Rough texture, weak bonding, repelling surfaces

• Sweet taste, flexibility, transparency

• Softness, colorfulness, heat resistance

• Stickiness, strong bonding, spreading and covering surfaces

How does surface tension contribute to stickiness?

• Surface tension causes molecules to stick together

• Surface tension only affects the color of the molecules

• Surface tension has no effect on stickiness

• Surface tension repels molecules from each other

Discuss the effect of temperature on stickiness.

• Temperature has no effect on stickiness

• Stickiness is only affected by pressure, not temperature

• Stickiness increases with higher temperature

• Temperature can affect stickiness by altering the viscosity of the substance.

Provide an example of an application of sticky molecules.

• Glass cleaner

• Toothpaste

• Adhesives

• Chewing gum

How does adhesion differ from cohesion in sticky molecules?

• Adhesion is the attraction between molecules of the same substance, while cohesion is the attraction between different molecules.

• Adhesion and cohesion are the same thing.

• Adhesion and cohesion have no relation to sticky molecules.

• Adhesion is the attraction between different molecules, while cohesion is the attraction between molecules of the same substance.

What role does surface tension play in the behavior of sticky molecules?

• Surface tension has no effect on the behavior of sticky molecules.

• Surface tension causes the molecules to stick together and affects their behavior.

• Surface tension causes the molecules to repel each other and spread out.

• Surface tension repels the molecules and prevents them from sticking together.

How does temperature affect the adhesive properties of molecules?

• It changes the mobility and interactions of the molecules.

• It causes the molecules to repel each other

• It makes the molecules stickier

• It has no effect on the adhesive properties

Name one real-world application of sticky molecules.

• Cooking oil

• Adhesives

• Chewing gum

• Balloons
