Equation of state, an Uncommon card
In physics and chemistry, an equation of state is a thermodynamic equation relating state variables, which describe the state of matter under a given set of physical conditions, such as pressure, volume, temperature, or internal energy.

Power 140 (ATK + DEF): stronger than 70 % of WikiCards cards.
The facts on the card
The card carries these facts from its Wikipedia article.
- Most modern equations of state are formulated in the Helmholtz free energy.
- Equations of state are useful in describing the properties of pure substances and mixtures in liquids, gases, and solid states as well as the state of matter in the interior of stars.
- Though there are many equations of state, none accurately predicts properties of substances under all conditions.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Equation of state article was read about 39,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 74 and blocks with 66: each hit it takes is cut by 26 %.
How to get Equation of state
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.
