(c) quasi static cycles (d) semi- reversible cycles​

Answer 1

(a) reversible cycles......

Answer 2

Answer:

The Carnot cycle is a theoretical thermodynamic cycle that is extensively studied in thermodynamics and used as a standard for comparing the efficiency of real heat engines. The Carnot cycle is a reversible cycle, i. H. it can run both forward and backward while maintaining thermal equilibrium with its surroundings.

Explanation:

The Carnot cycle consists of four phases:

• isothermal expansion,
• adiabatic expansion,
• isothermal compression,
• adiabatic compression.

During the isothermal expansion phase, heat is supplied to the system and the temperature of the working medium is kept constant. During the adiabatic expansion phase, the working fluid expands without heat transfer, resulting in a drop in temperature.

During the isothermal compression stage, heat is extracted from the system and the temperature of the working fluid is kept constant. Finally, during the adiabatic compression phase, the working substance is compressed without heat exchange, which causes the temperature to rise.

The Carnot cycle is a quasi-static cycle in the sense that it is a very slow process that can be approximated as a series of equilibrium states. This allows the Carnot cycle to be analyzed using thermodynamic terms such as entropy and work, which would not be possible in a real, fast cycle.
