1. What is the difference between charging by conduction and charging by induction?

A- During induction, charges move between objects that briefly touch; during conduction, charges move between objects that are rubbed together.

B- During conduction, charges move between objects that briefly touch; during induction, charges move between objects that are rubbed together.

C- During induction, charges move between touching objects; during conduction, charges are redistributed within an object that is near another object.

D- During conduction, charges move between touching objects; during induction, charges are redistributed within an object that is near another object.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance

tracks, burrows, eggshells, nests, tooth marks, or gastroliths
