Make a concrete example of a linear dynamical system that observes a stable equilibrium, unstable equilibrium and no equilibrium or fixed point respectively.
An unknown material, m1 = 0.26 kg, at a temperature of T1 = 89 degrees C is added to a Dewer (an insulated container) which contains m2 = 1.6 kg of water at T2 = 24 degrees C. Water has a specific heat of cw = 4186 J/(kg⋅K). After the system comes to equilibrium the final temperature is T = 32.8 degrees C.
Part (a) Input an expression for the specific heat of the unknown material.
Part (b) What is the specific heat in J/(kg⋅K)?

An ideal gas (the weight is m kg) in an idealized piston-cylinder assembly undergoes a series of
processes from state 1 to states 2, 3 and 4. Each state is at equilibrium. The gas can be modeled as a closed
system. Ignore changes of KE and PE. The states are fixed by the following properties in the table:

Note: State 1 to 2 is a constant-temperature process. State 2-3 is a constant-volume process. State 3-4 is a
constant-temperature process.
