Suppose you have 2.5 kg of steam occupying 6.5 m^3 at a pressure of 1.013 x 10^5 Pa. When the steam condenses to water, it occupies a volume of 0.55 m^3 If the latent heat of vaporization of water is 2.26 x 10^6 j/kg, what was the change in the water's internal energy?
AT = 0
m = 2.5 kg
V. = 6.5 m^3
P = 1.013 x 10^5 Pa
Vf= 0.55 m^3
L = 2.26 x 10^6 j/kg
Q is coming out of the system
W is done on the system
