The facts on the card
The card carries these facts from its Wikipedia article.
- It is a single-phase or multiphase fluid flow that occurs spontaneously through the combined effects of material property heterogeneity and body forces on a fluid.
- When the cause of the convection is unspecified, convection due to the effects of thermal expansion and gravity/buoyancy can be assumed.
- Convective flow may be transient or steady state.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Convection article was read about 90,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 78 and blocks with 72: each hit it takes is cut by 29 %.
