Chem 103 Module 6 Questions and Correct
Answers/ Latest Update / Already Graded
Kinetic Molecular Theory (KMT)
Ans: 1.) Gases consist of tiny particles that move at different
speeds and in every possible direction in constant motion
2.) The size of gas particles is much smaller than the distance
between them; most of the volume of gas is empty space
3.) There is no force of attraction or repulsion between gas
particles; because molecules are so far apart from each other
4.) They undergo billiard-ball-like collisions (elastic) with the
walls of the container and with each other
gas laws are derived from KMT
if temp is increased...
Ans: -speed and kinetic energy of gas molecules increase,
pressure increases
-pressure held constant by increasing volume, greater distance
traveled by molecules so decreased collision frequency
if volume is decreased

Ans: frequency of collisions increases, distance decreases,
pressure increases
more molecules=
Ans: more volume
total pressure=
Ans: sum of partial pressures
Kinetic Energy (KE)
Ans: the energy of particle motion
1/2mv^2
The same amount of any ideal gas at the same temp will have
the same KE
Average Kinetic Energy
Ans: averaged energy over all gas molecules in the sample
KE(bar on top)= 3/2 RT
R=8.314 J/molK
