Question

The gas that gives the highest fractional conversion of heat to work in an isobaric process is:

• A. Monatomic gas
• B. Diatomic gas
• C. Polyatomic gas
• D. All types of gases give the same fractional conversion

Hint:

In an isobaric process, gases with fewer degrees of freedom (monatomic gases) typically perform better in terms of energy conversion.

Answer 1

The Correct Option is A

In an isobaric process, the fractional conversion of heat to work is highest for monatomic gases.
This is because the specific heat capacity for monatomic gases is the smallest, meaning that they require less energy to do a given amount of work.
