Which of the statements relates real-world use of charging processes?

• Flowing of electron during charging of cellphone.

• Dislodging of protons during lightning.

• Boiling a pot of water in the stove.

• Flowing of neutrons during charging by friction.

________ defines the process that happens when an object gains or loses an electron.

• Gaining

• Losing

• Charging

• Grounding

Which of the statement DOES NOT show comparison between the three methods of charging?

• Conduction and Friction involves contact between objects to charge.

• During the three methods of charging the protons and electrons were dislodged and they flow

• Friction, Conduction, Induction causes an object to be charged

• During the three methods of charging, the electrons were dislodged

This Illustration shows what type of charging process?

• By Friction

• By Conduction

• By Transmission

• By Induction

Among the statements given, which statement shows the contrast between the three methods of charging?

• Charging by friction happens when an object is rubbed; Charging by Conduction happens when a neutral object is in contact with a charged object; Charging by Convection happens when hot air rises, cold air sinks.

• There are no differences between the 3 methods of charging.

• Charging by friction happens when an object is rubbed; Charging by Conduction happens when a neutral object is in contact with a charged object; Charging by Induction happens when an object is charged without actual contact with any other charged object.

• Charging by friction and charging by conduction is the same while Charging by Induction happens when there is no contact between objects.
