QUESTION:
Problem 28E
What is the change in entropy of 0.130 kg of helium gas at the normal boiling point of helium when it all condenses isothermally to 1.00 L of liquid helium? (Hint: See Table 17.4 in Section 17.6.)
ANSWER:Solution to 28E
Step 1
Mass of Helium gas =0.13kg
Temperature of Helium gas =4.216K………….(Boiling point of Helium taken from the table)
Latent heat of vaporization =20.9x103J/kg
Latent heat of fusion= (-20.9x103J/kg)
