It traps air, which is a very good insulator of heat.

yes.glass wool is one of the sound absorbing material while ground glass is not.
Glass wool is a more effective sound-absorbing material compared to ground glass. Glass wool consists of fine glass fibers that trap sound waves, reducing noise pollution and improving acoustic insulation. In contrast, ground glass is typically denser and less porous, making it less effective at absorbing sound. Therefore, for soundproofing applications, glass wool is the preferred choice.
When a glass rod is rubbed with wool, electrons are transferred from the wool to the glass rod, making the rod negatively charged. This transfer of electrons causes the glass rod to become statically charged, meaning it has an excess of negative charge.
Rockwool is made from natural rock minerals and is considered to be more environmentally friendly. Glass wool, on the other hand, is made from recycled glass bottles and can create airborne dust during installation. Both materials are used as insulation in buildings and have similar thermal and acoustic properties.
Yes
the rod slightly attract each other
The described action will leave the wool sock positively charged, as electrons will be transferred to the glass rod.

Yes, rubbing a glass rod with a wool cloth can create static electricity by transferring electrons between the two materials. This process causes the glass to become positively charged and the wool to become negatively charged, resulting in static electricity buildup.
Rubbing a glass with a piece of wool creates friction, causing electrons to be transferred between the two materials. The glass becomes negatively charged as it gains electrons, while the wool becomes positively charged as it loses electrons. This phenomenon is known as static electricity.
