Phase II Electricity and Magnetism

Question 1

Matter

Answer 1

Has mass and occupies space. Based on temperature.

• Solid - low temperature, atoms stick together.
• Liquid - with added energy, atoms can move around but remain together.
• Gas - with even more energy, atoms can disassociate from each other.
• Plasma - high temperature, electrons will dispersed when released and emit EM radiation.

Question 2

Neutrons

Answer 2

Very massive NOT fundamental particle found in the nucleus of an atom and have NO charge

Question 3

Protons

Answer 3

Very massive NOT fundamental found in the atom’s nucleus with POSITIVE charge

Question 4

Electrons

Answer 4

Very little mass, FUNDAMENTAL particles with negative charge found in the outer rings of an atom

Question 5

Photons

Answer 5

Packets of energy, no mass

Question 6

Quantum Leap

Answer 6

When energized (by photons) electron jump from one energy shell to another

Question 7

Energy

Answer 7

Does NOT have any mass, does NOT occupy space, cannot be created nor destroyed. Capacity to cause change. Total energy = KE + PE

Question 8

Kinetic Energy (KE)

Answer 8

Associated with movement

Question 9

Potential Energy (PE)

Answer 9

Associated with height; it is stored energy.

Question 10

Photoelectric Absorption/Emmission

Answer 10

A photon absorbed/emitted by an electron. Energy equals exactly the quantum leap

Question 11

Ionization

Answer 11

High energy photon is absorbed by an electron, the electron jumps to infinity

Question 12

Photo-electric effect

Answer 12

Excess energy manifests as kinetic energy

Question 13

Fusion

Answer 13

Light nuclei combine to form new heavy element

Question 14

Fission

Answer 14

Heavy nuclei divide to form new light elements
