Is an explosion more likely to happen when pumping very fine powders or when pumping powders that consist of much larger particles?
fine powders as it has greater charge
Suggest one way that the risk of an explosion could be reduced.
Idea of earthing
What happens to the structure of an atom to change the atom into an ion?
Atom loses one electron
Certain insulating materials can become charged
You can charge certain insulating materials by rubbing them together.
Electrons can move from rod to cloth. Electrons are negatively charged particles, which move from the rod to the cloth during rubbing. Protons, which are positively charged particles, never move. The rod becomes positively charged as it loses electrons. The cloth becomes negatively charged as it gains electrons.
