It also excludes the ______ energy of motion.
Answer
kinetic. It also excludes the kinetic energy of motion. From the Internal energy article on Wikipedia.
Which of these cards hits hardest (highest ATK)?

Which of these Wikipedia articles is read the most in a year?
Answer
Probability theory. Probability theory 130,000 · Explosion 95,000 · Internal energy 70,000 · E-segment 56,000 Wikipedia reads over a year.
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 also excludes the kinetic energy of motion.
- The notion of internal energy is present in the expression of the first law of thermodynamics as a state variable, as originally formulated by the german scientist Rudolf Clausius, one of the founders of thermodynamics who is also the author of the notion of entropy as a state variable.
- The total internal energy of a system cannot practically be measured.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Internal energy article was read about 70,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 71 and blocks with 41: each hit it takes is cut by 16 %.
How to get Internal energy
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.
