Term
 Steps for naming an ionic compound
Definition
 1. say metal 2. remove suffix from non metal3. add "ide" to new suffix4. Say together
Term
 Steps for naming a covalent compound
Definition
 1. 1st element with prefix2. Add "ide" as new suffix, with prefix
Term
 Number Prefixes
Definition
 1. mono2. di3. tri4. tetra5. penta6. hexa7. septa8. octa9. nona10. deca
Term
 how much is 1 mole of a substance
Definition
 6.02 * 10^23
Term
 Symbol for Alpha particle
Definition
 He2+
Term
Definition
 e-1
Term
 Symbol for Neutron Emission
Definition
 n
Term
 Elements above this atomic number are naturally radioactive
Definition
 83- Bismuth
Term
 Elements above this atomic number are naturally radioactive
Definition
 83- Bismuth
Term
 What can happen to a lone neutron?
Definition
 it splits into a proton and electron
Term
 What is transmutation
Definition
 the changing of an element due to radioactive emissions
Term
 What is Fission
Definition
 When a radioactive substance decays and the amount of the product is less than the amount of the reactants
Term
 What is fusion
Definition
 When a radioactive substance decays and the amount of the product is more than the starting amount
Term
 What is a critical mass
Definition
 the amount of a radioactive substance needed to produce a chain reaction
Term
 What is the equation for energy
Definition
 energy=(mass)*(speed of light)^2
Term
 What is it called when a substance has exactly no KE
Definition
 absolute zero
Term
 What is the equation for converting Celsius to Kelvin
Definition
 Celsius+273=kelvin
Term
 What is the First Law of Thermodynamics
Definition
 Whenever heat flows into or out of a system, the gain or loss of thermal energy equals the amount of heat transferred
Term
 What are the three types of heat transfer and how do they differ?
Definition
 conduction-objects make contactconvection- circular motion of hot and cold in a fluidradioaction- electro magnetic energy
Term
 What is the second law of thermodynamics
Definition
 Heat always transfers from hotter objects to cooler objects unless acted upon by another force
Term
 What is the 3rd Law of Thermodynamics
Definition
 No system can reach absolute zero
Term
 What is the difference between a motor and a generator?
Definition
 motor- converts electricity to movement (fan turning)generator-converts movement (fan turning) to electricity
Term
 What is the equation for calculating heat energy of a substance
Definition
 Heat energy= kg*specific heat*change in temperature
Term
 What is specific heat?
Definition
 The property of a substance that shows how much energy is required to change 1 kg of that substance by 1 degree
Term
 What unit is heat energy measured in
Definition
 jules
Term
 What is the major difference between a mechanical and electromagnetic wave?
Definition
 mechanical- requires medium to travel throughelectromagnetic- can go through vacuums
Term
 Example of mechanical wave
Definition
 sound
Term
 Example of electromagnetic wave
Definition
 light
Term
 Two types of mechanical waves and their differences
Definition
 Transverse- the wave moves perpendicular to the direction of the energy (spring)Longitudinal- the wave moves parrallel with the direction of the energy
Term
 What is rarefaction and compression
Definition
 occurs in longitudinal waves, rarefaction is the rarity of a wave due to stretching and compression is the squeezing together of part of a wave
Term
 What is a wave
Definition
 energy
Term
 what is amplitude
Definition
 the distance from a mid point to crest of a wave
Term
 What is a wavelength
Definition
 the distance from one wave crest to another
Term
 What is the equation for frequency and its unit?
Definition
 Frequency= 1/period
Term
 What is the equation for wave speed
Definition
 frequency * wavelength
Term
 What is the period
Definition
 the time it takes to complete a vibration
Term
 What is the frequency of sound
Definition
 pitch
Term
 Equation for period of a wave
Definition
 frequency * wavelength
Term
 Why does the same pitch on different instruments not sound the same?
Definition
 Every central pitch resonates background pitches in multiples of two, every instrument has different intensitys of these multiples
Term
 What are nodes?
Definition
 the point where crests and troughs cancel each other out/ cross over on a wavelength
Term
 Why do we see lightning before we hear thunder?
Definition
 Velocity of light is significantly greater than the velocity of sound
Term
 Two types of interference?
Definition
 constructive- crest to crest/trough to troughdestructive- crest to trough
Term
 Why are tsunamis so small in deep water and then jack up in shallow water?
Definition
 because in deep water the amplitude of the crest is tiny because the wave length is so long, but then the shallow water causes the wave to move upwards and increases the amplitude
