Answer
Option-c
Two adiabatic and two isothermal process
Work Step by Step
The Carnot cycle is an idealized thermodynamic cycle that consists of four reversible processes:
$1.$ Isothermal Expansion: The gas expands isothermally (at constant temperature) while absorbing heat from the hot reservoir. During this phase, the temperature remains constant.
$2.$ Adiabatic Expansion: The gas continues to expand, but now the expansion is adiabatic (no heat exchange). During this phase, the gas does work on the surroundings, and its temperature decreases.
$3.$ Isothermal Compression: The gas is compressed isothermally (at constant temperature) while releasing heat to the cold reservoir. During this phase, the temperature remains constant.
$4.$ Adiabatic Compression: The gas continues to be compressed adiabatically (no heat exchange). The work done on the gas increases its temperature.
