AUTHENTIC QUESTIONS WITH VERIFIED
ANSWERS


Which state of matter has the greatest Kinetic Energy? - correct-answer -Gas has
the greatest KE, because the particles are far apart and moving fast




What are the three types of Intermolecular Forces? - correct-answer -(1)
Hydorgen Bonding
(2) Dipole Attraction
(3) Dispersion Forces




What do you call a solid changing to a gas? - correct-answer -Sublimation




What are the values for STP? - correct-answer -0 Celcius or 273 Kelvin
1 atm = 101.3 kPa = 760 mmHg

, 2


Why is the pressure of a gas directly proportional to the number of particles? -
correct-answer -P1/N1 = P2/N2....because pressure is caused by collisions of gas,
and more particles means more collisions




Why is the volume of a gas inversely proportional to pressure? - correct-answer -
P1 x V1 = P2 x V2...because as volume increases, there is less opportunity for
particles to collide




Why is the pressure of a gas directly proportional to temperature? - correct-
answer -P1/T1 = P2/T2....because as temperature increases, KE increases, which
makes collisions happen more often and harder




Why is the volume of a gas directly proportional to temperature? - correct-answer
-V1/T1 = V2/T2....because as temperature increases, KE increases, and the
particles spread aout




PV=nRT - correct-answer -Pressure x Volume = # of moles x Gas Constant x
Temperature




Dalton's Law of Partial Pressure? - correct-answer -P total = P1 + P2 + P3 ...
