Why does the substance in the column of the thermometer go up when it is heated?
When the substance in the column of a thermometer is heated, its temperature increases. As the temperature increases, the particles in the substance move more energetically and spread out, causing the substance to expand and rise up the column. This expansion is what causes the fluid to rise and indicate a higher temperature reading on the thermometer.
What happens when you put a clinical thermometer into boiling water?
A clinical thermometer is designed to measure body temperature accurately, not high-temperature environments like boiling water. Putting a clinical thermometer into boiling water can damage the thermometer, resulting in inaccurate readings and potentially posing a safety risk. It's best to use thermometers specifically designed for measuring high temperatures in such situations.
Why does mercury level goes down for a very short time when a mercury-in glass thermometer is placed in hot water?
The exterior of the bulb of the thermometer expands first, resulting in the mercury level to go down. After that the mercury in the bulb expands more than the glass bulb, resulting in the subsequent rise of the mercury level.
What is difference between a clinical and a laboratory thermometer?
A lab thermometer normally is very long and has a wide range of measurement with uniform degrees spread out over the distance and has a mark showing how far into the measured substance it go to get accurate measurements.A clinical thermometer has a larger bore at the bottom where the contents can expand without measurement occuring then a tiny bore where the degrees are spread out at the body temperature. Thus at room temp, all the liquid is down in the big area and only as it gets up to 95 degree or so is the liquid expanded in the reading area. This allows the thermometer to be physically short and easy to handle while having wide degrees to be easy to read. There is also a trap so that the column separates leaving liquid in the tiny bore to read instead of dropping quickly on removal. The liquid has to shaken out of the tiny bore back into the big one.
Is anthracene a sublimable substance?
Yes anthracene is a substance that can sublime.
Why does the substance in the column of the thermometer go up when it is heated?

This expansion is what causes the fluid to rise and indicate a higher temperature reading on the thermometer.
Why does the thermometer go down when the temp gets cold?
A thermometer measures temperature based on the expansion or contraction of the liquid or metal inside it. When it gets cold, the molecules inside the thermometer contract, causing the liquid or metal to shrink, which in turn results in the reading on the thermometer going down.
What is the relationship between how deep you go in the Earth and how hot it gets?
the deeper you go the hotter it gets
Why does the liquid in thermometer go up the tube when it gets hotter?
Heat causes mercury in the thermometer to expand, where as when it is cooled, it contracts.
Will ammo go off in a hot car?
No, the only way it ever gets that hot is if it is on fire.
Is Colombia hot?
overall in Colombia its hot or rather warm. But it really depends where you go. for example if you go to Bogota its cold ,...it gets quite warm in the day but in the afternoon to the night it gets chilly and sometimes freezing. If you go to the coast or to Cali well there its HOT!
Why do you use mercury thermometer?
As tempertature rises, the Mercury in the thermometer expands, causing it to go up. As temperature decreases, the mercury in the thermometer contracts, causing it to go down on the scale. However, mercury thermometers are very dangerous if it breakes and gets on your skin. so it it reccomended to use an electric thermometer. these thermometers use thermoelectric current to measure temperature. ergo. they are safe if they break cheers <3 -Eli
What is the red line on a thermometer?
The red line on a thermometer typically indicates the level to which the mercury or other liquid inside the thermometer should rise when measuring temperature. This line is often used as a reference point to ensure accurate readings. When the temperature rises, the liquid expands and moves up the tube, reaching the red line to indicate the current temperature.
What makes the mercury go up and down the fine tube of the thermometer?
When anything, in this case mercury, gets warmer it gets larger and vice versa, when it gets cooler it gets smaller. As the mercury gets warmer and larger it fills more of the tube and when cooler it fills less of the tube.
Where should you visit in Cornwall?
well it gets a bit busy in the summer but it is best to go in spring or summer in the summer there are more things to do in winter it gets a bit chilly in autum it is ok but not the best and spring is hot cold hot hot and a few people go then not to much not to less
What cause your heater to go from hot to cold when the car warms up?
because it needs to cool down if it gets too hot
The term heat conductivity is best defined by the ability of heat to do what?
Take Thermometer and put it in the hot water -Calculate Temparature-go with the formula of Conductivity of heat
