A rubber balloon is rubbed with a PVC pipe and the rubber balloon becomes positively charged. Why is this? a) Because the rubber balloon gained protons from the PVC pipe. b) Because the rubber balloon gained electrons from the PVC pipe. c) Because the rubber balloon lost protons to the PVC pipe. d) Because the rubber balloon lost electrons to the PVC pipe
Electrons are lost or gained when the ballon is rubbed with a PVC. As the rubber ballon lost electrons, it will have more protons, hence the positive charge. (More protons than electrons in the ballon).
