Question

A) An ideal gas in a piston - cylinder assembly expands isothermally, do ing work and receiving an equivalent amount of energy by heat transfer from the surrounding atmosphere. Is this process of the gas in violation of the Kelvin - Planck statement of the second law? Explain. B) The isentropic turbine and compressor efficiencie s are defined from a fixed initial state to a special final ................... C) In the limit, it is possible for a process of a closed system to be internally reversible, but there could be irreversibilities within the surroundings. Give an example of such a process.

Explanation / Answer

a)no,because kelvin-plank statement states that the sole effect of which is to absorb energy in the form of heat from a single thermal reservoir and to deliver an equivalent amount of work.

(b)it depends on enthalpy at the entrance state to enthalpy at the exit state at isentropic process.

(c)exmple is otto cycle
