The number of properties there are, and what they are.

What is 2, Chemical and Physical?

100

This is the formula for Density. 

What is D= M/V or Density = Mass ÷ Volume

100

The Definition of Conductivity and Insulator

Conductivity: ability of a substance to allow electricity or heat to pass through it freely

Insulator: any substance that does not allow heat or electricity to pass through it freely

These are two electroscopes to detect the charge of an object. 

What is a Pith Ball Electroscope and and Metal Leaf Electroscope?

100

These are two examples of static electricity in everyday use. 

What is Photocopier: Positively charged toner sticks to negatively charged paper, recreating the image.

Spray Paint: Spray paint gun is positively charged, which makes every paint particle positively charged, repelling each other and creating a fine mist.

The number of types of changes in matter there are, and what they are.

What is 2, Physical and Chemical?

This is the density of a solid object with a mass of 222.5g and a volume of 25cm3.

What is 8.9g/cm3

Definition of Proton, Neutron, Electron

Proton: Found in the nucleus of the atom,  POSITIVELY CHARGED, p+

Neutron: Found in the nucleus of an atom,            NO CHARGE = NEUTRAL, n0

Electron: Found orbiting the nucleus, always moving, NEGATIVELY CHARGED, e-

The descriptions of Pith Ball and Metal Leaf Electroscopes.

Pith Ball Electroscopes:

  • Metal ball (aluminum) suspended on a piece of string

Metal Leaf Electroscopes:

  • Metal leaves (thin) will separate or repel in the presence of a charged object

200

This is Ohm's Law, with each letter explained.

What is V = I x R?

V = Potential Difference 

I = Current

R = Resistance

300

This is the definition of Qualitative.

What is physical qualities or observations described using our senses Ex: Shape, Colour.?

300

This is the volume of a substance (l x w x h) and then the density is this, when the these are the dimensions L = 3cm W = 6cm H= 4cm and the mass is 80g

What is:

The volume of substance = 72cm3?

The density of substance = 1.11g/cm3?

300

The definition of Static Electricity

What is an imbalance in electric charge on the surface of an object?

300

True or False: The electric force between two charged objects is stronger when they are farther away from each other

What is False?

300
These are the 3 ways an object can become charged. 

What is 

1. Friction

2. Contact

3. Induction

400

These are three chemical changes.

What is:

A new substance is formed 

 The new substance has completely different properties 

Atoms involved are rearranged

400

This person had the "Billiard Ball" theory that, all atoms were identical, indivisible, and made up of one part.

Who is John Dalton?

400

This is the definition of what the Electrostatic Series is.

What is a list of substances and their tendency to hold electrons, this can be used to determine the charge on an object. It also shows Objects that tend to LOSE or have a WEAK HOLD ON electrons, that becomes POSITIVELY CHARGED. As well as objects that tend to GAIN or have a STRONG HOLD ON electrons, that become NEGATIVELY CHARGED. 

400

The definition of Electric Discharge. 

What is the sudden movement of static charge between two object. It is when electrons move from one object to another very fast.  Ex: When you touch a metal doorknob, the electrons can move from you to the doorknob. You feel a shock and may even see a small spark

400

Fill in the Blank: To charge a neutral object, the neutral object must be ___________ to give the electrons a pathway to move through.

What is grounded?

500

This type of change shows changes in size and form as well as changes in state Ex.    Ice     ⇔    Liquid Water ⇔     Water Vapour also no new substance is formed.

What is a Physical Change?

500

This person Performed the “gold foil experiment” found that a positive core exists = “nucleus”, found also that there were negative charges, “electrons” that are outside the nucleus. Also noticed that a lot of space exists in the atom, also developed the “nuclear model”.



Who is E. Rutherford?

500

These are the Laws of Electric Charges

1. Objects that are oppositely charged = ATTRACT
                         + =><= -

2. Objects that are similarly charged  (like charges )   = REPEL      - <= => -           + <= => + 

3. Charged objects (+ or -) are ATTRACTED to neutral objects        + =><= 0               - =><= 0

500

This is how Lightning is created.

What is when positive charges move to the top of the cloud where ice and snow crystals form, at the same time negatively charged water droplets move to the bottom of the cloud. The ground below develops a positive charge, causing a really big difference in charge between the cloud and the ground, which produces a surge of electrons. Causing a step ladder, where positive charges climb up from the ground and negative charges climb down from the cloud, eventually meeting causing a flash of connecting atoms. Then the lightning heats up surrounding air, making it expand really fast. This causes a sudden, loud sound known as thunder.

500

This is how Objects charge by Friction, Contact, and Induction.

Friction: Static electricity is produced by rubbing different materials together, this causes both surfaces to obtain a different charge. One object loses electrons (becoming positively charged), the other object gains electrons (becoming negatively charged)

Contact: Occurs when a charged object is brought into CONTACT with a differently charged object or neutral object , electrons will transfer between the two objects in an attempt to balance the charge

Induction: An electric charge is transferred from one substance to another WITHOUT DIRECT CONTACT ,the induced charge is opposite to that of the charged object producing the charge
