DAT flashcards

1 atm = ? 760 mm Hg = 760 torr
standard temp. and pressure 273.15 K and 1 atm (used with problems involving pressure)
standard conditions 0 C, 298 K (used in problems involving enthalpy, entropy, gibbs free energy)
Boyle's gas Law PV = k; P1V1= P2V2 at const. temp., the volume of gas is inversely proportional to its temp.
Law of Charles and Gay-Lussac V/T = k; V1/T1 = V2/T2 at const. pressure, volume of a gas is directly proportional to its absolute temp.
K --> Celsius conversion T(K) = T(C) + 273.15
Avogadro's Principle at const. temp. and pressure, the volume of the gas will be directly proportional to the number of moles of gas present n/V = K; n1/V1 = n2/V2
Ideal Gas Law PV = nRT
Gas constant R = ? 8.21 x 10^-2 (L*atm)/mol*K)
volume of 1 mol of gas at STP 22.4 L
determining partial pressure of a gas Pa = Pt Xa where Xa = n(a)/n(t) (moles of A/total moles)
Assumptions of the Kinetic Molecular Theory gas particles... 1. vol.'s are negligible 2. exhibit no intermolecular interactions 3. are in continuous, random motion, undergoing collisions with other particles and container walls 4. collisions are elastic 5. KE proportional to temp.
fusion transition from solid to liquid
alpha particle helium nucleus
beta decay beta particle = e conversion of neutron to proton Z increases by 1 in daughter cell Z decreases by 1 in positron decay
