connexus students:
1. Pure water and pure salt are poor conductors of electricity. When salt is dissolved in water, the resulting solution conducts electricity well. Which statement explains why this occurs with these substances?
a: The process of dissolving makes the electrons in their atoms free to move.
(they put this in the first paragraph of the second page)

2. Which statement correctly describes the conductivity of the specified material?
a: Gold has a high conductivity.
(metals are good conductors and since gold is a metal it has high conductivity)

3. A person plugs a power cord into an electrical outlet in the wall. The power cord is covered in black rubber. Which statement is an accurate description of the materials?
a: Electrons would easily move through the person if there was no rubber around the wire.
(plastics such as rubber are insulators so it would stop the electrons from traveling thru the wire)

4.Which statement describes a similarity between conductors and insulators?
a: They can both be used in an electric circuit.
(an example is like the question above, the charger is an electric circuit)

Lol I use this website once in a while for help and I just thought I would post answers here and the reasoning behind it cus this website has helped me a lot thx yall.
