Ratio of specific heats γ = cp/cv: decide its magnitude For a gas, compare the ratio of specific heats γ = c<sub>p</sub>/c<sub>v</sub> with unity. Choose the correct relation.

Difficulty: Easy

Correct Answer: Greater than one

Explanation:

Concept/Approach

  • For ideal gases: cp − cv = R > 0 ⇒ cp > cv.
  • Therefore γ = cp/cv > 1.

Final Answer
Greater than one
