Evaluate the partition function of a classical ideal gas
consisting of N molecules of mass m confined to a cylinder of
vertical height L which is in a state of thermal equilibrium at
constant temperature T in a uniform gravitational field of
acceleration g. Calculate the specific heat and why it is larger
than the free space value.

A Vi = 10-3 m3 chamber of a gas bottle contains some argon gas
(atomic weight = 0.040 kg/mole) at a pressure of 104 Pa and a
temperature of 34� C. 1)What is the number density of atoms in this

A metal, M, of atomic mass 56 amu reacts with chlorine to form a
salt that can be represented as MClx. A boiling point elevation
experiment is performed to determine the subscript x, and
therefore, the formula of the salt. A 29.2 g sample of the salt is
dissolved in 100.0 g of water and the boiling point of the solution
is found to be 377 K. Find the formula of the salt. Assume complete
dissociation of the salt in...

An atomic nucleus of mass m traveling with speed v collides
elastically with a target particle of mass 2m (initially at rest)
and is scattered at 90°. (a) At what angle does the target particle
move after the collision? (b) What are the final speeds of the two
particles? (c) What fraction of the initial kinetic energy is
transferred to the target particle?

Instead of giving atomic masses for nuclides as in Appendix B,
some Tables give the mass excess, ?, defined as
?=M?A, where A is the atomic number and
M is the mass in u.
A)Determine the mass excess, in u, for 42He; 126C; 10747Ag;
23592U.
b)Determine the mass excess, in MeV/c2, for
42He; 126C; 10747Ag; 23592U.
A mass of m = 1 Kg of an ideal gas (gas constant R= 278 J/KgK)...
A mass of m = 1 Kg of an ideal gas (gas constant R= 278 J/KgK)
undergoes two polytropic processes. During the first process
temperature increases from 27 0C to 237 0C
and volume decreases from 1 m3 to 0.3 m3.
During the second process temperature increases to 473 0C and
volume is constant. The isentropic exponent of the gas is 1.4.
Determine (a) Polytropic exponents (b) missing properties of the
gas (c) heat and work of the first process...

4.
(a) Derive an integral expression for the probability of a gas
molecule of mass m, at temperature T is moving
faster than a certain speed vmin.
(b) A particle in the atmosphere near the earth’s surface
traveling faster than 11 km/s has enough kinetic energy to escape
from the earth’s gravitational pull. Therefore, molecules in the
upper atmosphere will escape if they do not have collisions on the
way out. The temperature of the upper atmosphere is about 1000K....

Some free radical chemical reactions start with the
photodissociation of I2 molecules into Iodine atoms (gas phase) by
light with a wavelength shorter than about 792nm. A 100.0mL glass
tube, pressure= 55.7mtorr and temperature 25.0C contains I2
molecules What minimum amount of energy must be absorbed by the
iodine in the tube to dissociate 15% of the the molecules?
