Heat capacity ratio, an Uncommon card
In thermal physics and thermodynamics, the heat capacity ratio, also known as the adiabatic index, the ratio of specific heats, or Laplace's coefficient, is the ratio of the heat capacity at constant pressure to heat capacity at constant volume.

Heat capacity ratio quiz: 3 questions
Three questions on the Heat capacity ratio card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
The ______ P and V refer to constant-pressure and constant-volume conditions respectively.
Answer
suffixes. The suffixes P and V refer to constant-pressure and constant-volume conditions respectively. From the Heat capacity ratio article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Heat capacity ratio. Heat capacity ratio 63 · Four Books and Five Classics 59 · Blood cell 56 · Pigtail 51 ATK in WikiCards.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- It is sometimes also known as the isentropic expansion factor and is denoted by γ for an ideal gas or κ, the isentropic exponent for a real gas.
- The symbol γ is used by aerospace and chemical engineers. γ = C P C V = C ¯ P C ¯ V = c P c V, where C is the heat capacity, C ¯ the molar heat capacity, and c the specific heat capacity of a gas.
- The suffixes P and V refer to constant-pressure and constant-volume conditions respectively.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Heat capacity ratio article was read about 53,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 63 and blocks with 25: each hit it takes is cut by 10 %.
How to get Heat capacity ratio
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
