9. why can’t there be a temperature lower than absolute zero?

Temperature lower than absolute zero is not possible. Lower than absolute zero a gas contain negative pressure and volume which is not possible. temperature is the energy created by moving atoms absolute zero is a complete stand still you can make particles move to the end of the universe but the coldest temperature will be stuck at the point where atoms are motionless

hope that helped :)

what are the statements? x

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete
