Asteam turbine operates at a boiler temperature of 450 k and an exhaust temperature of 300 k. what is the maximum theoretical efficiency of this system?

The maximum theoretical efficiency of the system is the one corresponding to the efficiency of a Carnot cycle operating between the same temperatures of the system:

where  and  are the cold and hot temperatures, respectively.
In our problem,  and , therefore the maximum theoretical efficiency is

So, 33%.

B) as the temperature increases, the kinetic energy of the particles increases.|-/
