So, by taking the derivate of the expression of the vapor pressure with respect to

SOLUTION TO HOMEWORK #3

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:
i
M1U1f M2U2f M1U1i M2U2 0
Then, we can make the appropriate substitutions:
M1Cv,1 T1 f T1i M 2C
SOLUTION TO HOMEWORK #2
3.2
Starting with the energy balance, we get:
from problem statement, we can eliminate the heat, shaft work, and expansion work. Also,
since we are at steady state, all the d/dt terms cancel out.
In addition, because the temperatur
