Who Am I? — Natural Laws & Processes Edition

Which law of nature am I?

• Discovered in the early 19th century, I explain why carbon dioxide stays trapped in your soda until the cap is opened.
• I describe how the amount of gas dissolved in a liquid depends on the pressure above it, keeping soft drinks fizzy under a sealed lid.
• Beyond beverages, I also govern how gases like oxygen dissolve into the bloodstream, maintaining nature’s delicate balance of exchange.

Which natural process am I?

• I transform fallen leaves, dead plants, and animal remains into simpler building blocks that enrich the earth.
• Driven by microbes like bacteria and fungi, I break down complex organic matter and release nutrients that help plants thrive.
• Beyond nourishing the soil, I also influence the planet’s carbon balance, subtly shaping the air we breathe.

Which scientific principle am I?

• Formulated in 1908, I describe how a population’s genetic makeup can remain in balance when no external forces act upon it.
• Named after two mathematicians, I predict that allele frequencies stay constant unless altered by mutation, selection, or migration.
• Beyond representing stability, I provide a baseline for detecting shifts in genetic variation, helping scientists trace how populations evolve over time.

Which fundamental constant of nature am I?

• I am reported to have been measured for the first time by the Danish astronomer Ole Christensen Rømer.
• I connect electricity and magnetism, quietly emerging from Maxwell’s equations in the 19th century.
• By remaining finite, I ensure that the past and the future remain distinct.
