What is the
Avogadro constant
?
6.022 x
10^23
, the number of atoms in
12g
of
carbon
.
What is the equation for the total number of atoms or molecules in a substance?
n is the number of moles of the substance.
A)
n - number of moles of substance
What is the
kinetic theory
of matter?
Model that describes all substances as made of
atoms
,
ions
, or
molecules
arranged differently depending on the phase of the substance.
What is an
ideal gas
?
A model of a gas including
assumptions
that simplify the behaviour of real gases.
What are the assumptions made in the
kinetic model
for an ideal gas?
Gas contains large number of
atoms
, moving in random directions
Atoms occupy a
negligible
volume compared with the volume of the gas
The collisions of atoms with eachother and the wall are
elastic
(no kinetic energy is lost)
Time of collisions between the atoms is negligible compared to the time between the collisions
Electrostatic forces between atoms are negligible
except
during collisions
What is the equation for
molar mass
M
?
m = n x M
What is relationship between
pressure
and
volume
for a gas?
If the temperature and mass of gas remain constant, the pressure of an
ideal gas
is inversely
proportional
to its volume.
What is
Boyle's Law
?
The pressure of an ideal gas is inversely
proportional
to its volume, provided that the mass of gas and the
temperature
do not vary.
What is the relationship between
pressure
and
temperature
for a gas?
If the volume and mass of gas remains constant, pressure of an
ideal gas
is directly
proportional
to its absolute temperature.
What equation do you get when you combine the
gas laws
?
For an
ideal gas
, if the conditions are changing from an intial state to
final state
:
What is the
molar gas constant
?
The constant in the equation of state of an
ideal gas
8.31 J⋅K −1 ⋅mol −1
What is the
equation of state
for an ideal gas
pV
=
nRT
What is the root mean square speed (r.m.s. speed)?
The square root of the mean square speed of all particles in a gas.
What is the
mean square speed
?
The mean of the squared
velocities
of all the particles in a gas.
What is the equation for
r.m.s
speed?
Equation that equals
root mean squared
speed.
What is the equation when you combine pressure and volume with the r.m.s. speed?
N is the number of particles in the gas
M is the mass of each particle
C is the mean square speed of the particle
What is thre
Maxwell-Boltzman
n distribution?
The distribution of the speeds of particles in a gas.
What does the
Maxwell-Boltzmann
distribution look like on a graph?
T2
is a higher temperature than
T1
which is a lower temperature.
What is
molar mass
?
The mass of one
mole
of a substance.
What is the
Boltzmann constant
?
A constant that relates the mean
kinetic energy
of the atoms or molecules in a gas to the gas
temperature
.
What is the equation for
Boltzmann constant
?
The value for Bollzmann constant is 1.38 × 10−23 J/K
What happens to
particles
speed at different temperatures?
At a given temperature, atoms in different gases have the same
kinetic energy
However as the particles have different masses their
r.m.s.
speed is different
Internal energy
of an ideal gas
Assumption of an ideal gas is that the
electrostatic forces
between particles in the gas are negligible during a collision
Meaning there is no
potential energy
in an ideal gas
Doubling the
temperature
of an ideal gas doubles the average
kinetic energy
of the particle, doubling the kinetic energy
