|Chemical Engineering Thermodynamics is the relationship between heat, work, and systems in energy processes. Thermodynamics consists analytical and theoretical methods that can be applied to machines for energy conversion.
Laws of thermodynamics
The Zeroth law of Thermodynamics says that that if A is in thermal equilibrium with B, and also B is in thermal equilibrium with C, then C is also in thermal equilibrium with A and vice versa.
- The zeroth law of thermodynamics
|For example the length of a mercury column can be used as a measure to compare the temperatures of the two other objects.
Suppose a system undergoes a process by heat and work transfer then the net heat supplied Q and the net work input W will be equal to the change of internal energy of the system. i.e
- First law of thermodynamics, i.e Conservation of Energy LAW
Delta ( U ) = U2 – U1 = Q + W
Here U1 & U2 are internal energy of the system ar state1 & 2, respectively. If system undergoes in a complete cycle then U1 = U2,
This leads to Q + W = 0
The second law of thermodynamics says that there is no heat engine which can be more efficient than a reversible heat engine working between two fixed temperature i.e.
- Second law of thermodynamics
n< n(max) = n(c )
We can say W will be restricted to an upper limit Wmax i.e.
W < W(max) = Q.n(c )
