Question

10
which of the following is most likely to be able to be statically charged by friction? (1 point)
glass of water
metal spoon
flying pan
balloon

Explanation:

• Glass of water: Water is a conductor and charges can move freely, so it is not easy to be statically charged by friction.
• Metal Spoon: Metals are conductors. Electrons can move freely in metals, so they are not easy to be statically charged by friction.
• Frying pan: Usually made of metal (a conductor), electrons can move freely, not easy to be statically charged by friction.
• Balloon: Made of rubber (an insulator). When rubbed with other materials (like hair), electrons transfer between the two materials. Since rubber is an insulator, the transferred electrons cannot move freely away, so the balloon can be statically charged by friction.

Answer:

Balloon
