Knowing how to use a thermometer

[mobb]

i got a question when is knowing how to use a thermometer VERY IMPORTANT for us?

Who exactly is "us"? A group of young students who want to be scientists one day?

What's so confusing about it? Stick it in whatever you're measuring and wait a bit - then read how high the alcohol/mercury went. If it's an infrared thermometer, point and click. If it's a thermocouple, read the big numbers on the display (assuming you don't have to calibrate it).

if it's an anal thermometer I'd say it's very important to get it right the first time

When it's very important to know what temperature something is at.

 

[mobb]

when is important to know the temperature anywhere inside ur house, outside in the cold, the warm, when is it important

 

[sameandnot]

when is it very important to know anything?!?

(refer to brewnog)

 

[sameandnot]

ya know... "the importance of knowing" is always subjective and therefore relative.

 

[sameandnot]

my 2 cents:
perhaps it is more important to know who asks the question? ...

For example, water freezes at 0 degrees C (32 degrees F). When you are landing an airplane on a cold wet runway, if the runway is at -1 degrees C, you could crash because of ice; but if it is at +1 degrees C, you are OK.

Wrong. There is a big difference between landing on an icy runway and landing on a wet runway, for example. People with responsibilities (like pilots, and airport managers) can't afford to use cop-outs like that.

When we have no sense of temperature ourselves?!

of course, you are right Aether.

strawberry and banana smoothies are made with ice.

 

[sameandnot]

i hate 'em hot!

Did you forget to pull the carb heat lever? On any decent size of runway, there's no need for brakes, so ice isn't that big of a deal. You don't get weird **** like pressure ridges on a reasonably well maintained strip.

Mobb, the primary times that temperature is critical are in physiology and delicate experiments about chemistry, physics, etc.. For instance, you have to monitor body temperature very carefully during surgery.

i was just asking a question for my project, this is supposedly to be a science forums not a playing forums

 

[mattmns]

One of these days you may have a kid/s and s/he may seem sick and you might want to take their temperature to find out if s/he is sick. Or you might be sick yourself one day, and usually it is a good idea to take your temperature.

General discussion is the playing bit, sorry mobb!

Hey Aether;
I must confess that I was thinking of the kind of things that I drove rather than those flying hotels, but I would still contend that the runway ice itself wouldn't have caused an accident like that without the accompanying storm conditions. I might be wrong, but I've never heard of it happening in calm weather.

Hello Danger, perhaps it is more an issue of being able to steer than anything else. An airliner can use up quite a bit of runway in order to come to a complete stop.

 

[Danger]

There is that. I tend not to think on that scale, being, as my signature implies, a guy who once parked a Cessna in someone's back yard.

I figured that mobb would naturally picture an airliner when I said "airplane"...back yard, eh? Did you break anything important?

 

[Danger]

Naw. I was practicing short-field TO's & landings, and there it was. (It was actually a pretty big yard, but I like to omit that part. ) It belonged to someone I knew, and I had permission to do it.

That's probably one of the prettier crash landing scenes I've seen... all the color contrasts...

 

[Danger]

And more importantly (sorry to abandon the comedy here) it looks like one that everybody lived through.

Unfortunately not: Updated: 4:58 a.m. EST (09:58 GMT), December 9, 2005 -- A Southwest Airlines jet skidded off a runway in a heavy snowstorm at Chicago's Midway Airport Thursday night, sliding into an intersection and killing a young boy in a car. Another car was also hit by the Boeing 737 and eight other vehicle passengers were in serious condition, said Cortez Trotter, the Chicago Fire Department commissioner.

Crap! That sucks.

 

[tribdog]

Just goes to prove the old saying. Flying is safer than driving.

I am not getting any closer to heaven this way. someone needs to stop me before I talk next time

The SW Flight 1248 was landing on runway 4R (6446 ft / 1965 m), which is not a long runway, after circling the airport for about 30-35 minutes. Possibly the aircraft landed long on the runway, and ran out of runway. It would be interesting to learn how long (or even if) the pilot used reverse thrust.

Visibility was poor, and the temperature was about 26°F (-3°C).

Anybody following the story might find this useful.

For anyone venturing outside in the winter, it would be very important to know about the temperature, and dress accordingly. Either must must read a thermometer or one must receive the information from someone who does.

If one has a hot liquid and on has to pick up the container, then perhaps it would be advisable to know what temperature it is, especially if one is planning to pick up the container with one's bare hands.

If one is serving a hot beverage, then perhaps it is also wise to know at what temperature the liquid is before serving.

Water above about 120°F (49°C) is considered hot with regard to contact. Water boils at 212°F (100 °C), which is usually the temperature at which one makes tea.
