Question
Chapter 5, Problem 5.15NP
Interpretation Introduction
Interpretation:
The decrease in temperature when 2.25 moles of water initially at 310 K and 1650 bar pressure is brought to 1.30 bar in a reversible adiabatic process needs to be calculated
Concept Introduction:
A process is said to be adiabatic if there is not transfer of heat (q) between the system and surroundings i.e. q = 0
The entropy change (ΔS) associated with a process is the ratio of the heat transferred (q) and temperature (T)
For a reversible adiabatic process, q = 0 therefore, ΔS = 0

A 0.250 mol nitrogen initially at 50 °C with a volume of 8.00 L is allowed to expand reversibly and adiabatically until its volume has doubled. Calculate the value of ΔHwhen Cp = 7/2R.

Consider a sample of water vapour, which expands reversibly and adiabatically from
97.3 Torr and 400 cm3 to a final volume of 5.0 dm3. Take y = 1.3. Calculate the final
pressure of the sample.
A sample consisting of 2.0 mol CO2 occupies a fixed volume of 15.0 dm3 at 300 K. When it is supplied with 2.35 kJ of energy as heat its temperature increases to 341 K. Assuming that CO2 is described by the van der Waals equation of state (Topic 1C), calculate w, ΔU, and ΔH.
