What are adhesive bonds responsible for?

• Occurring between an adhesive's molecules and the molecules of whatever it's sticking to

• Holding the glue or tape's own molecules together

• Forming weak, reversible bonds

What is the main reason why a glued surface can't be reattached without new glue?

• The drying process makes the bonds irreversible

• The cohesive bonds are weak

• The solvent evaporates when exposed to air

• The adhesive bonds are weak

What type of bonds does tape form when applied to a surface?

• Van der Waals forces

• Chemical reaction bonds

• Cohesive bonds

• Adhesive bonds

What determines a tape's stickiness?

• The type of adhesive polymers used

• The thickness of adhesive spread onto the backing

• The proportion of elastic component and solvent

• The type of backing material

Which type of glue may form the strongest bonds?

• Milk protein casein

• Vegetable starch dextrin

• Cyanoacrylates (super glues)

What is the advantage of duct tape in an emergency situation?

• It is compatible with a wider range of surfaces

• It has instantaneous stickiness

• It has higher resistance to heat and shearing

• It forms irreversible bonds

What is the main reason why liquid glues don't work in zero gravity?

• They have weak adhesive bonds

• They require a solvent to work

• They have weak cohesive bonds

• They need enough real estate where surfaces touch
