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.
What makes mercury in a thermometer go up and down?
Change in temperature is what cause the Mercury to expand up (hotter) or shrink down (colder).
What does a thermometer do and why is it useful?
A thermometer is used for checking temperatures. Either it be througt a person, out side, or food. It tells you if you have a fever or not. If your food ex. turkey, is cooked all the way through. It also lets you know how to dress depending on the temperature out side.
How does a thermometer work to measure temperature accurately?
A thermometer works by using a substance, such as mercury or alcohol, that expands or contracts based on temperature changes. This substance moves up or down a calibrated scale to indicate the temperature. The accuracy of the measurement is determined by the precision of the scale and the sensitivity of the substance to temperature changes.
Ho does a thermometer measure temperature?
A thermometer measures temperature by using a substance that expands or contracts with temperature changes, such as mercury or alcohol. As the substance heats up or cools down, it moves along a scale marked on the thermometer, providing a reading of the temperature.
When a thermometer is turned upside down why does it keep the same reading as when it was right side up?
nothing happens
What is the exploratory robots work envelope?

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.
Is horizontal up and down or side to side?
Horizontal ; Side to side Vertical ; Up and down .
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.
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.
What happens to the values as you move up the left side a min thermometer?
They Increase.
Does butterology work?
No. The Mythbusters tested it, and recorded an even split of butter-side-up to butter-side down.
What makes hydrolics work?
hydrolics work on high pressure fluid pushing pistons up or down. a hydrolic arm that goes up will probably work on a lever with the arm on one side and the piston on the other side that goes down, and the piston is powered by pressurized fluid pushing the piston down.
Is vertical up and down or side to side?
Vertical is up and down and horizontal is side to side.
Why mercury go down and up suddenly in a thermometer?
Depending on Atmospheric Pressure
Is lengthwise up and down?
It can be either up and down, or side to side.
