If one thermometer is above ice cube and other is below at the same distancewhich thermometer reading changes and why?

If both thermometers were at room temperature before you arranged them above and below the ice cube, then the one below should show a greater change, and sooner, than the one above. The ice cools the air around it, causing the air around it to become more dense than the air at room-temperature. The cool air then sinks, right past the lower thermometer.

platinum resistance thermometer
Is there air in a glass thermometer?
Yes, above the mercury or the other liquid.
What does a falling barometric reading?
Any reading above 1012 milibars.
When thermometer is laid ouside the sun does it measure suns temperature or air temperature?
If a thermometer is laid out in direct sunlight, it will not measure the temperature of the air surrounding it. It will measure the temperature of the heat directly reaching it.
What determines the range of a thermometer A. length of stem B. volume of bulb C. thickness of bulb D. volumn of stem?
None of the above
What do you do before taking an axillary temperature?
Shake down the thermometer before using, if the reading on the thermometer is 94.0º F or above.
Which equipment is most useful when measurin Barometer and voltmeter Light meter and barometer Voltmeter and thermometer Thermometer and light meter the two environmental changes mentioned above?
A thermometer and light meter are the most useful when measuring two environmental changes.
What changes takes place in the liquid inside a thermometer when the thermometer is placed into something hot?
The liquid in thermometers expands when temperature increases (and contracts when temperature decreases). When it expands, the only place for it to expand 'to' is up the thermometer (into the empty space above it).
Thermometer use to measure temperature above 1250 celsius?
platinum resistance thermometer
If you look outside and see that the thermometer is reading -1.00 degree Celsius You see puddles are not frozen Why?
(1) It takes a while to freeze. (2) The earth may be warmer than the air above it.
The Fahrenheit and centigrade scale have the same numerical reading at what temperature?
The numerical reading on the Fahrenheit thermometer may be higher, lower, or equal to the numerical reading on the Celsius thermometer. -- If either one reads below -40°, then both do, and the Fahrenheit reading is the lower one. -- If either one reads above -40°, then both do, and the Fahrenheit reading is the higher one. -- If either one reads -40°, then they both read -40°. -- Whatever the temperature, the Fahrenheit reading is always 32° greater than 1.8 times the Celsius reading.
3 degrees celsius below zero is written as?
On a thermometer, temperatures above zero are written as positive and below zero as negative. How will a reading of 3 degrees celsius below zero be written?
Is there air in a glass thermometer?
Yes, above the mercury or the other liquid.
Effect on thermometer reading if the thermometer is removed from the liquid when thermometer is being read?
It would depend on a contingency of variables. Being, how hot is the substance that it is being removed from, the temperature of the room, how long it takes from the time removed from the liquid until it is read, and the type of thermometer reading device.
Are there standards for thermometer deployment?
standards for thermometer deploymentAnswerYes. In a white louvred box (Stevenson Screen) with the sensors 1.1 metres above ground level.
What is a high reading?
Any reading above 1012 milibars.
Why would the alcohol thermometer need to be contained in a shelter?
If the thermometer had direct sunlught on it, it would give a false reading because it would be directly heated by the sun's energy in the rays. The idea of temperature measurement is to measure the temperarure of the immediate medium in which the thermometer is placed. The shelter provides this environment. For accurate internationally acceptable readings the shelter has to conform to specific dimensions and design criteria, as well as a certain height above the ground. Direct sunlight could also cause the thermometer to burst, depending on the maximum temperature scale on the instrument.
