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

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
and since
1 = 2
Then, we can make the

#Problem 2:
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.

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
