[A] Precipitation from cold air masses sometimes falls as balls of ice called hail.
(1) Suppose one such ice ball falls from an altitude of 6100 meters a
Work Calculations
[1] A gas is allowed to expand at constant pressure until it reaches its final volume. It is then
cooled at constant volume until it reaches its final pressure. The initial state of 1.00 mol of a
dilute gas is P1 = 2.97 atm, V1 = 0.95 L,
THERMODYNAMICS OF GASES
Basic Tools:
PV = nRT
dE = dw + dQ
E = 3/2 RT per mole
dw = -PdV
We will employ the above tools to construct expressions for the work done and the
heat exchanged during various types of processes. The questions will lead you

Expanding the Treatment of Heat and Matter
[1] A bimetal strip is 10cm long at 300K and made of iron and molybdenum. When heated to 500K, it
bends. Calculate the radius of curvature given that the strip is 1mm thick (0.5mm between centers of
the metal lay

The second part to one of the heat and temperature problems was concerned with
determining the fraction of helium atoms which would have speeds greater than the
escape speed of 11 km/s at a temperature of 300K.

Physics Lab Requirements and Procedures
The physics lab is an "open" type of lab. This is convenient because it allows
you some flexibility in the times that you may come to the laboratory to do
your experiments. It does require vigilance on your part to
