Celsius never devised nor used the scale that now bears his name.

I filmed this in Uppsala in the summer of 2012! So I've been thinking about this idea for a very long time. I'm glad to finally have it out there in the world.

Anyone can enlighten me regarding higher temperatures? How do we measure melting temperature of steel ( I know with light and so on) but how do we relate temperature to the light?

6:40 Mishap: Water doesn't consistently freeze at 0,0001°C but melts then. Liquids often don't have a freezing point, but get subcooled without condensation seeds.

This is an excellent video! The information is very precise. So many articles online have the history wrong. As a USA citizen, I recently ordered 3 Celsius outdoor thermometers from Russia with 0 in the middle going up to 50 and going down to 50. I had never seen the Celsius temperature scale represented in this way. I could easily live with it now. I think a lot of kids in school here in the USA now get more exposure to both the metric system and Celsius temperature scale. Perhaps in a few decades the USA will go fully in on both which it should.

FYI it’s just Kelvin. Not degrees Kelvin as you said a couple of times.

Fahrenheit is a better system of measurement for casual layman purposes, and Kelvin is a better system for scientific measurements. Celsius is irrelevant, change my mind.

"There is no objectively good reason for preferring an ascending scale over a descending one." But there is an absolute lowest possible temperature (0°K) and no upper limit*, so it makes sense to count upwards. Granted, this was not know in Celsius' time. *As temperature continues to increase with the addition of energy, there is, _in principle_, an upper limit: when all of the energy of the universe has been harnessed. However, this is not attainable, and I do not think we have a guess as to how much available energy there even is.

and in 2019 they abandoned the triple point and simply defined the Kelvin in terms of Joules and the Boltzmann constant: "The kelvin, symbol K, is the SI unit of thermodynamic temperature. It is defined by taking the fixed numerical value of the Boltzmann constant k to be 1.380649×10^−23 when expressed in the unit J ⋅ K^−1, which is equal to kg ⋅ m^2 ⋅ s^−2 ⋅ K^−1, where the kilogram, metre and second are defined in terms of h, c and ΔνCs."

I didnt get how water can reliably define temperature regardless of ambient pressure.. I must have heard it wrong..
mehmud 19 dagar sedan
temperatures are relative to water... because you 0 degress doesn't tell you what? If I just 4KM, would you that make any sense? if I say 4KM from Point A, that would make sense, similary 0 degress from water at freezing point, means temprature is equal to water's freezing point, number is just a calculation to figure stuff out, and yes you heard it wrong because calculatin to be independent of pressure is taken as constant, because pressure will affect freezing point

There is maybe a reason to have a higher number for a higher temperature (and it's funny to image we'd say "lower temperature" when it got warmer if the scale was still flipped). Temperature is a measurement of energy, while "coldness" in itself doesn't exist, it's just the absence of thermal energy. You have to add energy to a system to increase the temperature, and you have to remove energy from a closed system to lower the temperature. I think it's nice that you can convert energy usage and temperature change with positive coefficients.

Note: celsius is no longer defined as the triple point of water. It's now defined as making boltzmann constant a fixed value

Whilst at school, I remember temperature measurements that we were taught changed in name from Centigrade to Celsius. That was in the 80's, long after 1948 so I'll blame that lag on the British educational system and the cost of school books 😂

I noticed SVfrom recently started recommending me Veritasium videos (including this one) but with the titles and descriptions translated in French (I live in QC, Canada), though of course the videos' content is still in English. Is that a new SVfrom feature or is this channel trying to get more views in some specific markets?

2:19 I don't agree, because if something gets larger, more or heavier, it's counted upwards... 1 apple, 2 apples - 1 Meter, 2 Meters, 5kg is lighter than 10kg... So it makes sense that something hotter is described by a bigger number than something cold.

Why was Kelvin defined by setting the tripple point to such an odd number? I thought it took the temperature difference of one degree from Celsius and placed the zero mark at the absolute zero point...

5:28 well, the melting point depends on the pressure, have a look here: It's just a really small difference at these low pressure differences, therefore not important here.
Carl Hansen
Carl Hansen 2 månader sedan
Water is unique in this regard, where the melting point increases as pressure decreases. Most substances do the exact opposite.
Carl Hansen
Carl Hansen 2 månader sedan
That's why the triple point and freezing point of water are not exactly the same. And why Kelvin is defined with the triple point at 273.16 K, even though the Celsius to Kelvin conversion has an offset of 273.15 K.
