Why can a mercury thermometer be used only at high temperatures?
A mercury thermometer can go down to -30 deg C
Is thermometer a type of manometer?
Not quite; This is what the first source said about how a thermometer works; This liquid is sometimes colored alcohol but can also be a metallic liquid called mercury. Both mercury and alcohol grow bigger when heated and smaller when cooled. Inside the glass tube of a thermometer, the liquid has no place to go but up when the temperature is hot and down when the temperature is cold. In other words, the thermometer goes up or down due to the expansion of the alcohol or mercury due to the heat. After reviewing the second source, you will see that the columns go up and down due to the atmospheric pressure. If it goes up and down due to atmospheric pressure it is a manometer. A manometer does not work if it is not exposed to the atmosphere. A thermometer is sealed off to the outside. This is another reason why a thermometer is different from a manometer.
Is it normal for the temperature to go up on a thermometer when it has come out of a ice-water bath for 1 minute?
Assuming that the surroundings are above the freezing point of water - yes - it is normal for the temperature on the thermometer to go up. It may still remain elevated even if plunged back into the ice bath since the thermometer has mass and can absorb some energy while out of the bath. There is also the phenomena that in some thermometers even when the temperature drops, the thermometer fluid sometimes remains elevated unless you "shake down" the thermometer.
When is the body cooled?
the body is cooled when you eat cold ice or when you go to a place that is cold
Why doesn't the liquid in the thermometer move when you turn it upside down?
The liquid in a thermometer does not move when turned upside down because of the properties of the liquid used (usually mercury or alcohol) and the vacuum-sealed tube design of the thermometer. This design prevents the liquid from freely moving when the thermometer is inverted.
What causes liquid in thermometer to travel up and down in tube?
Heat causes Mercury in the thermometer to expand, where as when it is cooled, it contracts.
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.
Why does the liquid in a thermometer sink down?
This liquid is sometimes colored alcohol but can also be a metallic liquid called mercury. Both mercury and alcohol grow bigger (expand) when heated and smaller (contract) when cooled. Inside the glass tube of a thermometer, the liquid has no place to go but up when the temperature is hot and down when the temperature is cold. Its the process of expansion and contraction
Why can a mercury thermometer be used only at high temperatures?
A mercury thermometer can go down to -30 deg C
Why the alcohol level in a thermometer goes down when it's cold?
When the temperature drops, the alcohol in the thermometer contracts and takes up less space. This results in the alcohol level appearing to go down in the thermometer.

Why mercury go down and up suddenly in a thermometer?
Depending on Atmospheric Pressure
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.
Why doesn't the mercury on a medical thermometer go down when it's removed from the body?
The mercury on a medical thermometer does not go down when removed from the body because the mercury expands to a certain level when it comes in contact with body heat, and even after it's removed, it does not contract back immediately. The thermometer needs to be shaken or reset for the mercury to go back down to its starting point.
The dry-bulb thermometer is cooled by evaporation when the wind blows True or False?
true
Does salt melt ice?
no...........try it with a thermometer, just put ice in a cup, add salt then check the thermometer...........instead of going up, it will go down
What makes mercury go up and down a thermometer?
the heat and temperature that causes it to rise and fall.
