A thermometer is like if we measured speed by crashing a car into a barrier and gauging how much it made the barrier shake.
I mean, it would work, lol.
It’s really an average of all the traffic that was interrupted
PV=nRT, or T=(PV)/(nR) You know, with gasses, temperature can be examined with respect to many factors.
I speak of gasses as many of us are just fartin’ around on Lemmy. Pressure I tell you. We’ve all just spent the day under a lot of pressure, or should I say…gasses?
Jolene! Jolene! Dont you steal my ham. …it hasnt been temperature tested, mam!
By that logic:
Officer, I couldn’t have been speeding, the average speed of all the cars was below the speed limit!
Was it really though?
Was it really though?
Including the speed of the parked cars, yes :)
Warm atoms go wheeeeeee!
When I was in elementary school, one of my classmates pronounced it “thermo meter” and I had to watch the science teacher struggle for a good 30 seconds to decide if he was going to correct him or not.
I like to do that with a lot of the o’meters, just for fun.
Acceler-o-meter and seis-o-meter are my favorite. Weirdly least fun: kil-o-meter.
Pedometer is my favorite of these. How many pedo’s ya get in today?
and what the teacher did?
Corrected him. lol.
For anyone confused.
Most other languages do call it a thermo meter or similar. People who are not native English speakers will pronounce it wrongly when speaking English, because the word is the same - it’s just pronounced weirdly in both British and American English. The British and American pronunciations are not exactly the same on this, but they’re both
wrongdifferent from any other languages, except Greek.The English pronunciation is caused by English inheriting the Greek way of stressing the third last syllable on words of Greek origin. It makes no sense in my mind why they do it on compound words though. Meter is not Greek. It’s English, so they could’ve chosen differently, but they obviously chose the most annoying way to pronounce it.
There’s a few other words like that, but I don’t remember which…
Pedometer is the first one that comes to mind for me.
I don’t even want to know how that’s pronounced correctly. It’s obviously two words. Foot and meter. Wtf is a Dom?
Circumference is pretty bad too.
I think it’s the same as ther-MOM-iter. Pe-DOM-iter
Thermo meter Thermometer
Me: They are the same picture
Seriously though i did not understand which one I am pronouncing. I would usually read thermo meter and thermometer the same. When I try to differentiate by trying to make it sound together, or by trying to make more detatched, i just can’t and end up pronouncing the same
Ok. In English it’s pronounced third-MOM-meet-her.
In Spanish as well. Ter-MO-metro
Meter is not Greek.
Do you mean its pronunciation is not Greek?
Both thermo and meter are from Greek, but the combination didn’t exist until the 17th century
What you wrote before is confusing then.
I think we should start pronouncing molecules or particles like Hercules, just to be consistent
Now you’re just wrecking my mind.
Just as long they don’t wreck your testicles.
I think we can agree on that one.
In any of the languages that I know the pronunciation of, there are no differences in the pronunciation of deez nutz.
Hah. That reminds me of a joke I used to play on my wife back when cars had cd players. After we got in the car, about once a month I would come up with
“Hey can you go and get that CD for the ride?”
“What CD?”
“See Deez Nutz.”
Ha. Thanks. I’ll use that on my family today .
Mole-cue-leez?
Haha thanks! I was totally lost xD
Id like to see her in a speedo meter
Eyyy!
How do you meter a Speedo? I am but a stupid sexy space elf and do not understand your ways.
You look for tracks and pray to play
Wouldn’t it be speed and crowding simultaneously?
Also, where would infrared photons fit in this scenario?Hmmm, he says, reveling in his pedantry: Speedometers actually measure net displacement, and since thermal energy causes collisions on the small scale, but results in very little net movement for the particles, its not quite like a speedometer.
I like to think of it as a ball pit with one of those super bounce ball stacks in it.
I’ve heard this, but then I asked once what speed water molecules in a room temperature glass of water would be going. Are they like walking, driving, flying in a jet, or much faster? I was told my question didn’t have an answer since it didn’t really work that way or something.
I often wondered if the person answering just wasn’t able to make some assumption needed to answer because I didn’t state it in the question, or if saying thermometers measure speed is just wrong.
See figure 3 here: https://en.m.wikipedia.org/wiki/Thermodynamic_temperature
As mentioned above, there are other ways molecules can jiggle besides the three translational degrees of freedom that imbue substances with their kinetic temperature. As can be seen in the animation at right, molecules are complex objects; they are a population of atoms and thermal agitation can strain their internal chemical bonds in three different ways: via rotation, bond length, and bond angle movements; these are all types of internal degrees of freedom.
tl;dr Water be jiggly. Amount of jiggle is hard to put a number on
It would still be possible to answer the speed question, you just get different answers for different substances (and even phases of the same substance) at the same temperature.
Since something like water does have those additional ways to store energy, my guess is it would be slower at room temp than another liquid with less complex molecules that have about the same mass each. (If there is such a thing)
Also I expect different answers for each of mean, median, and mode speeds.
So if I were jiggling, I think I could come up with a speed. I’d figure out how far I’m moving, and how long it takes me to move. So I could measure from far left to far right of the jiggle (let’s say 18in.) and then how far to go from far left to far right and return to the original position. If that’s 2 seconds, then that’s 1½ feet per 2 seconds which can be converted to any other speed such as km/hr.
let’s say 18in.
Show off. 😠
I’m rather jiggly.
The jiggly argument is about not all parts moving at once or in one direction. If you jiggled to the right by taking one 18 inch step to the right, sticking your left arm straight left, waiving your right arm in a complete circle, holding your left foot 3 inches off the ground, and squatting down 10 inches how far have “you” moved?
How does the thermometer get its answer? I’d measure that part.
The answer by the thermometer is the temperature, which is based on more degrees of freedom. You’ll have to define some mapping between the other degrees and velocity.
My atoms sped up a bit during the decontamination scene.
Oh, great, now I have to rub one out again.
Well, speedometers are also speedometers for atoms
As we’re both Trekkies, I tell my spouse who likes it warmer all the time that they’re exposing us to unnecessary radiation leaks.
