Question 751: Thermodynamics & KTG

Question

The first operation involved in a carnot cycle is

Accepted Answer

In a Carnot cycle, the first process is the reversible isothermal expansion. Here's a brief explanation of the Carnot cycle sequence:
$$	extbf{Isothermal Expansion:}$$ The working substance expands at a constant high temperature, absorbing heat from the hot reservoir.
$$	extbf{Adiabatic Expansion:}$$ The gas continues to expand without exchanging heat, causing its temperature to drop.
$$	extbf{Isothermal Compression:}$$ The gas is compressed at a constant low temperature, releasing heat to the cold reservoir.
$$	extbf{Adiabatic Compression:}$$ The gas is compressed without heat transfer, which raises its temperature back to the initial high temperature.
Since the first step involves isothermal expansion, the correct option is:
Option A: isothermal expansion.

Answer
