Boltzmann constant quiz: 3 questions
Three questions on the Boltzmann constant card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
It is named after the ______ scientist Ludwig Boltzmann.
Answer
Austrian. It is named after the Austrian scientist Ludwig Boltzmann. From the Boltzmann constant article on Wikipedia.
Which of these Wikipedia articles is read the most in a year?
Answer
Boltzmann constant. Boltzmann constant 290,000 · Timothy Paul Jones 4,300 · Birmingham Accident Hospital 2,500 · Canon de 16 C modèle 1864 1,000 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 occurs in the definitions of the kelvin and the molar gas constant, in Planck's law of black-body radiation and Boltzmann's entropy formula, and is used in calculating thermal noise in resistors.
- The Boltzmann constant has dimensions of energy divided by temperature, the same as entropy and heat capacity.
- It is named after the Austrian scientist Ludwig Boltzmann.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Boltzmann constant article was read about 290,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 68 and blocks with 53: each hit it takes is cut by 21 %.
How to get Boltzmann constant
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.
