Describe how a system containing two gases can be in thermal but not in mechanical or chemical equilibrium. Describe how a system con-taining two gases can be in thermal and mechanical equilibrium but not in chemical equilibrium .

2)
Give an example of (a) a reversible isochoric process;(b) a quasistic, adiabatic, isobaric processes; (c) an irreversible isothermal process. Be careful to specify the system in each case.

3)
The thermodynamic temperature of the normal boiling point of nitrogen is 77.35 K. Calculate the corresponding value of (a) the Celsius, (b) the Rankine, and (c) the Fahren-heit temperature.

The answer of the 2nD Q:_
A)a frictionless pendulum swings back and forth
B)an isolated cylinder with frictionless piston is slowly expanded , the pressure remains constant
C)a cylinder with friction piston is expanded slowly, the temperature remains constant

The answer of the 3rd Q:
the relationship between the scales is;
T=273.15+t
R=(9/5)T
F=(9/5)t+32
so
a)t=-195.8
b)R=139.23
C)F=-320.44
