Derivation of internal energy being independent of volume

Derive C_v constant volume specific heat for regular and ideal

Derive C_p (ideal)

Derive adiabatic, ideal gas system constant values

Derive entropy for ideal gas

Describe the 4 laws of thermodynamics and give overall expression

Oth if 2 systems are in thermodynamic equilibrium with a third system, they are at equilibrium with e.o.

1st delta E = - delta W + delta Q

2nd thermally isolated system changing macrostate, entropy tends to increase

Not isolated, quasi static infinitesimal change gives delta S = delta Q / T

3rd at T tends to 0 K, S tends to a value S_0

Derive first general relation (maxwell)

Derive second general relation (maxwell)

Derive third general relation (maxwell)

Derive fourth general relation (maxwell)

Derive Carnot theorem

Name 3 useful formulae for ideal gases

Van der Waals equation of state and explain extra terms

Problem with the PV graph produced by van der waals equation of state

Explain how the problem with VdW eq. of state PV diagram was ‘fixed’ or explained

add the 5 labels and axis with a brief description of the graph

name the cycle, what its used in and fill in the covered terms.

What is the Rankine cycle, draw and describe.

How is the Rankine cycle adjusted to improve its practicality

Ideal and actual efficiency

Work ratio, definition and explanation

significance of the work ratio

when the W_in and W_out are reduced from their ideal values then the work ratio shows how significant the reduction in efficiency of the system will be, work ratio near 1, small difference, small work ratio, big difference.
