Which adhesive tool heats a solid glue stick to its melting temperature and extrudes adhesive when the trigger is pressed, though it lacks strength for permanent structures?

• A. Hot Glue Gun
• B. Safety Goggles
• C. Safety Glasses
• D. Dremmel Tool

Answer: (A)

A hot glue gun is the tool that heats a solid glue stick until it melts and then extrudes the adhesive when you press the trigger. It’s great for quick, temporary bonds and for lightweight materials, but the glue’s strength isn’t enough for permanent structures. Hot-melt bonds can soften with heat, moisture, or long-term loading, and they don’t provide the rigid, durable hold you’d need for structural assembly.

The other options aren’t adhesive tools: safety goggles or safety glasses protect your eyes, not apply glue, and a Dremel tool is a multipurpose rotary tool used for cutting, grinding, or sanding rather than melting and dispensing adhesive.
