Work done in a volume change
Q1. In thermodynamics I still don't understand how volume
expanding relates to work being done? Work is force ! distance
and volume is distance cubed.
Work dW = pA dx = p(A dx)
= p dV

A Cessna 182 airplane has a wing of area 16 m2. It weighs
1.4 103 N (about 3100 lb). In ight the airplane moves
through the air at 75 m/s (about 170 mi/h).

Entropy and randomness
Q1. If there is no change in temperature, does that mean there is
no change in entropy? [Misconception reversible isothermal
expansion, free expansion]
Entropy is a state function that describes the

streamlines close together at a
certain point, doesnt that mean
that a lot of uid is concentrated

Example: A tight fit
Aluminum rivets used in airplane construction are made slightly larger than the rivet
holes and cooled by dry ice (solid CO2) before being driven. If the diameter of a hole
is 4.500 mm, what should be the diameter of a rivet at 23.0C
Example: Heat loss during breathing
In very cold weather a signicant mechanism for heat loss by the human body is
energy expended in warming the air taken into the lungs with each breath.
(a) On a cold winter day when the temperature is 20C, what amount o
Solution
First guess : Ice is warmed to 0C, then all of ice melts,
then all ice ends up as liquid water at final temperature T .
Demand that Qice + Qpot = 0, solve for T .
Qice = (heat to warm ice from 10C to 0C) + (heat to melt ice) + (heat to warm liqui
Solution
Second guess : Ice is warmed to 0C, then all of ice melts,
then water is warmed to 100C, then some of the water vaporizes.
Demand that Qice + Qpot = 0, solve for fraction x of water that vaporizes.
Qice = (heat to warm ice from 10C to 0C) + (heat
