Correct. Consider that in Fahrenheit, 212 is boiling and 32 is freezing. 212-32 - 180. So the halfway point between freezing and boiling in Fahrenheit is 180/2 + 32 = 122 degrees. 122 degrees Fahrenheit is in fact the same as 50 degrees Celsius.

Because the freezing point is at a different temperature on the two scales. If both used 0 for freezing, then half of one would be half the other. But because of the offset, they do not stay linear with each other.

In other words, if (degF = A x degC), you would see the kind of relationship you posted. But instead, (degF = A x degC + B), where A= 1.8 and B = 32. That “+ B” throws everything off.

If you're a sports fan. Imagine that your team loses a lot of close hands. Instead of losing 2-1, 3-2, 4-2, etc., you get to lose one game REALLY badly, then barely win all of your other games. If you lose one game 30-0, and win the rest 1-0, the total goals might be the same, but your win record is suddenly very different.

Gerrymandering is essentially taking a couple of big losses (in voting districts) while racking up many narrow wins. Same vote total, very different outcome.

Because the calibration points for both scales are based on the state changes of water.

At standard pressure water melts (changes from solid to liquid) at 0°C / 32°F.

At standard pressure water boils (changes from liquid to gas) at 100°C / 212°F.

Since both scales are linear, 50°C, which is the midpoint between 0°C and 100°C, is equivalent to 122°F, the midpoint between 32°F and 212°F.

When a state or other political unit has to be divided up into districts, with each district electing a representative, GERRYMANDERING occurs when one political party creates the districts in a way that most benefits that political party.

The bond contract states. We will pay you $100 in 5 years time, and we will also pay you $5 per year.

This is expressed as a 5% interest rate on the bond. And it appears as if the government are repaying you the $100 that they borrowed when they initially sold the bond, but that part is not entirely true.

The government simply has a contract stating that they will pay $100 in 5 years time, and $5 per year for each of those 5 years. Then they put that contract up for auction.

If they have set their interest rate correctly, the market will settle on exactly $100 as the price of that bond, but it rarely goes that well. Instead they might settle on a price of $99.99 or literally any other amount. If the market buys the bonds for less than the "face value" then the interest rate was set to low, if the market settles on a price more than face value, the interest rate was too high.

It's all a bit of a balancing act. The interest rate (the profit) balances against the initial investment (the price of the bond). This is true in both the primary market (when the government initially sells the bond) as well as the secondary market (when the bond holder sells it to someone else).

there's a flat gap between the two temperature scales. What you're doing there is applying the wrong logic.

following your reasoning, 50C = 106F, so 25C = 53F, so 1C = 2.1F.

it's a logarithmic curve

Also, for every 1°C increase of temperature, you see 1.8°F increase. Not only do they not share a zero point, they increase at different rates. The only point °F = °C is -40. At any other point, if you were to plot temperatures in celsius and Fahrenheit, they'd be two straight lines diverging from eachother, the further you got from -40.

That video is soo amazing. the Fritz Haber one right?

It was a perfect combination of Chemistry and Psychology.

Take the amount of water that's inside a human body and just pour it all into a big bag. It sloshes around a lot and feels like a liquid, right? Your question is asking why people don't feel like that.

Well, take all of that water, and split it up among several billion teeny tiny boxes. Put all those boxes together in the shape of a human, and it'll contain the exact same amount of water as the big bag did, except now it'll feel solid because the water is all held within objects which have shape and structure.

In an actual human, those billions of teeny tiny boxes are all of the cells in the body.

Along with what others have said, here's an analogy. We need to breathe oxygen. H2o and co2 both contain oxygen but we definitely can't breathe them as our supply of oxygen. Technically having the atom doesn't mean it can be used the same.

It more specifically comes from a direct redrawn district example that looked like a salamander in the early 1800s, as approved by then Massachusetts governor Eldridge Gerry.

Is valve float the fact that the valves can't close fast enough?

>A better way to phrase it might be...why oxygen instead of Sulfur or Selenium? Because those are both in the same column on the Periodic Table, they have the same number of valence electrons and therefore can form double-bonds easily.

Certain bacteria for example, purple sulfur bacteria, use thiosulfate or hydrogen sulfide as a final electron acceptor instead of water. These are reduced into small grains of elemental sulfur instead. Others use various organic compounds like amino acids. These types of organisms are either obligate anaerobes which live in air-free hot springs that are rich in H2S, or else are microaerophilic, meaning they can tolerate low levels of oxygen but do not generally utilize it themselves. The latter live in relatively shallow, nutrient rich, stagnant ponds where there's an excess of organic materials. That is, the water has become stratified with a layer of oxygen poor, H2S rich water below a shallow oxygen rich layer on the surface.

These types of bacteria may predate the first oxygen-generating Cyanobacteria by hundreds of millions of years. The first photosynthetic organisms were non-oxygenic.

Selenium is vastly rarer in most environments. It wouldn't make sense to use it as a primary electron acceptor because it's rarity would be an extreme limiting factor on growth. Excess amounts of selenium are also toxic to most organisms. This is probably related to it's chemical similarity to arsenic.

>However, the obvious answer comes to mind at the same time: they're both solid at room temperature.

There are a number of bacteria that derive energy by oxidizing sulfur and/or various metal sulfide minerals into thiosulfate and sulfur dioxide. (Lithochemotrophs)

I'd figure they don't care about the alarm going off. What are people gonna do, call the police?

Celsius degrees and Fahrenheit are both different amounts (a difference of 1°C is a difference of 1.8F,) and the scales start at different places (0°C is 32F.)

So the actual conversion formula is that you have to multiply by 1.8 and then add 32.

Using terms such as "half the temperature" become meaningless statements unless using a temperature scale that starts at 0 at absolute zero.
