Question 1

When water of mass m and specific heat c is heated from absolute temperature T₁ to absolute temperature T₂, its change in entropy is

◦

cm ln(T₂/T₁)

◦

cm (T₂/T₁)

◦

cm (T₂−T₁)/T₁

◦

cm (T₂−T₁)/T₂

◦

cm (T₂−T₁)/(T₂ + T₁)

Question 2

Which answer below is not a statement of the second law of thermodynamics?

◦

Real processes proceed in a preferred direction.

◦

Energy does not flow spontaneously by heat from a cold to a hot reservoir.

◦

The entropy of the universe increases in all natural processes.

◦

In theory, heat engines working in a cycle employ reversible processes.

◦

You cannot construct a heat engine, operating in a cycle that does nothing but take heat from a reservoir and perform an equal amount of work.
