Joule Experiment extra material
In 1844-1854 Joule conducted an experiment to find out a relation between
the amount of work spent to bring about the liberation of heat and the amount of heat
liberated. The above graph is th
#Problem 1: 3.3
a) One kilogram of steam contained in a horizontal frictionless piston and cylinder is heated at
constant pressure of 1.013 bar from 125 C to such a temperature that its volume doubles.
Calculate the amount o

# Problem 1
a) The way to solve this problem is to begin with the system as the ball plus the water. Then, by
doing an energy balance, we get:
1 + 2 = 1 + 2
1 ,1 (1 1 ) + 2 ,2 (2 2 ) = 0
1 = 2
Then, we can make the

(although the temperatures are slightly different, the procedure to solve the problem is the same).
To begin with, we know how to deal with the ra
The heat of mixing of two liquids is given by Hmix=x1x2(A+B(x1-x2). A= -a1+ a2 T.
B= +b1- b2 T. Compute the difference between the partial molar and pure conponent
enthalpies as a function of x1 and T.
2 2 = 1
SOLUTION TO HOMEWORK #7
a. In order to solve this problem, we need to know what happens at the bubble point; at this
point, the first bubble is formed, so we can assume that all of the number of moles for the
components in the gas phase
