>A kilogram of steel is heavier than a kilogram of feathers
Isn't this technically true if you do the measuring under Earth's atmosphere where you have to account for buoyant forces? Granted the difference is minuscule, and it assumes by "heavier" you mean "apparent weight".

- tylerhou 4y agoIt’s also technically true if you ask about an ounce of gold vs. an ounce of feathers (gold is heavier) because gold ounces are different from feather ounces.
- bastawhiz 4y agoIt is not technically true. For one, the question didn't say "in Earth's atmosphere." But more importantly, if you get a kilogram of steel and a kilogram of feathers and put them on a consumer-grade scale on the planet Earth at standard temperature and pressure, they'll both show the same reading. If you are a person that needs a specific enough scientific answer to account for any ridiculously minuscule effect caused by the environment, you aren't asking it in such an off-handed way. If I asked "does ice float?" and got the answer "Ice floats on liquid water." that would be satisfactory. If I got the answer "Ice floats on liquid water if the ice is composed of hydrogen-1 atoms, or if it is placed in water composed of the same (or heavier) hydrogen isotopes." I would be dissatisfied because that's a confusing answer that nobody is reasonably looking for.
