How do you determine the force on a particle in an electric field?
Force=charge of the particle x the magnitude of the field F=qE
Fastest evaporating substance has the __________ vapor pressure
Sound travels fastest through
solids fastest, liquids and then air slowest
how are frequency and period related?
they are inversely related
Sound travels faster in _____ temps
What is the formula for the work done if you lift a mass from a to b?
W=mg(change in height)
always have a positive standard EMF (electron motive force)
Rapid processes are often adiabatic. Adiabatic means....
no heat is exchanged
If an ion has 6 ligands attached to a metal, it is said to be..... in shape
accept electron pairs
take a hydrogen proton
______ occurs at the cathode
reduction (i.e. Al(3+) becomes Al
the focal length of a sperical mirror is what?
the focal length of a spherical mirror is one halth the radius of the curvature
snells law says what
na sin θa = nl sin θl the index of refraction of two substances are related by the sin angle of the normal
the magnitude of an electic field on a point charge formula
E = (kq)/r
number of protons in a nucleus
What do standard reduction potentials show? (i.e. a large, positive)
a LARGE POSITIVE STANDARD REDUCTION POTENTIAL means that the thing will be REDUCED MORE EASILY
so if the thing with the larger potential GAINS ELECTRONS in the reaction, that is more favorable
The ANODE is the site of ___________
in a cell, current flows toward the
in a galvanic cell, electrons (not current) flow toward the
positive end (current flows to the negative end)
Adiabatic heating or cooling of a gas results from pressure change.
Work is done on or by the gas
, but t
here is no heat transfer
with the environment.
Adding resistors in parallel...____________. the overall resistance of the circuit
under alpha decay the daughter nucleus....
has 2 fewer protons and two fewer neutrons
