Question
Chapter 2, Problem 2.4CP
Interpretation Introduction
Interpretation:The difference between the reversible and irreversible expansions needs to be explained by discussing the degree to equilibrium that is maintained between the system and the surroundings.
Concept Introduction: In
Hence in reversible processes, both the system and surroundings are returned to their initial states. In general, all reversible processes are ideal processes and cannot occur naturally.
On the contrary, an irreversible process cannot come back to its initial condition. All spontaneous processes in nature are irreversible processes.
In an adiabatic process, the heat change is zero therefore the work done will be equal to the change in the internal energy.

15.) Which of the following systems has the greatest change in internal energy?
A.) A mixing of two ideal diatomic gases with equimolar amount and the same temperature and
pressure.
B.) An isolated container that contains two gases of different pressures separated by a frictionless
and movable piston. The gases are allowed to reach a mechanical equilibrium.
C.) Two blocks of similar metal that are in contact in an isolated container, one block metal has a
temperature of 100°C while the other block of metal has a temperature of 20°C. The two blocks of
metals are allowed to reach thermal equilibrium.
D.) An ideal gas that was allowed to expand freely and adiabatically.
E.) None of these.
Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to natural activities which increases heat-trapping greenhouse gas levels in Earth's atmosphere.
