Thermodynamic free energy quiz: 3 questions
Three questions on the Thermodynamic free energy card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
Therefore, only relative free energy values, or changes in free energy, are physically ______.
Answer
meaningful. Therefore, only relative free energy values, or changes in free energy, are physically meaningful. From the Thermodynamic free energy article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Thermodynamic free energy. Thermodynamic free energy 69 · Luminosity 66 · Magnetic tape 56 · Sister 50 ATK in WikiCards.
Which of these Wikipedia articles is read the most in a year?
Answer
Luminosity. Luminosity 91,000 · Magnetic tape 65,000 · Thermodynamic free energy 46,000 · Freight transport 35,000 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.
- The change in the free energy is the maximum amount of work that the system can perform in a process at constant temperature, and its sign indicates whether the process is thermodynamically favorable or forbidden.
- Since free energy usually contains potential energy, it is not absolute but depends on the choice of a zero point.
- Therefore, only relative free energy values, or changes in free energy, are physically meaningful.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Thermodynamic free energy article was read about 46,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 69 and blocks with 31: each hit it takes is cut by 12 %.
How to get Thermodynamic free 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.
