Thermodynamics

In an adiabatic process the following observations are obtained Find the value of γ of the working fluid

Pressure
20 bar
10 bar
Volume
5 lit
7 lit


For an adiabatic process PV γ =Constant
20×5 γ=10×7 γ
2=(7/5) γ
taking logaritham on both sides
log2= γ(log7-log5)
γ =0.3010/(0.8451-0.6990)
γ=0.3010 / 0.1461= 2.06
γ=2.06

Graphs and Level curves of functions of Two variables Definitions The set of points (x,y) in the plane where a function f (x,y) has a constant value f(x,y)=c is called a level curve of f The set of all points (x,y,f (x,y)) in space, for (x,y) in the domain of f, is called the graph of f The graph of f is called the surface z=f (x,y) The equation of the following hyperbolic paraboloid is `z=50+x^2-y^2`

IBM Q computing using QIS kit had made quantum computing very simple we can embed the python code for quantum computing in IBM Q notebook without much mess. We can run the code in simulator and interestingly we can run the code even in  IBM quantum computing device!!!!
