Why does the liquid in the thermometer go up and down when the weather changes?

the liquid in the thermometer rises because of the surrounding heat which causes a chemical reaction wihtin the substance which makes the liquid rises. When, the liquid sinks, itn is because the air has gotten cooler

Why doesn't the liquid in the thermometer move when you turn it upside down?
Because it doesn't.
What is the importance of thermometric liquids?
Thermometric liquid is the liquid found in the thermometer that help in the up and down movement of the temperature.
Cold weather slows down the process of?
a liquid to flow.
Why does the thermometer go down when cooled?
The cold reduces the temperature in the liquid inside the thermometer bulb. Most substances contract when their temperature drops so the liquid in the bulb occupies less space. this causes the column of liquid outside the bulb to become smaller.
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.
How does a glass thermometer works?
As the liquid in the thermometer is heated it expands, and the only way the expanding liquid can go is upward. As the liquid in the thermometer cools, it will contract, and the liquid will fall back down into the resevoir, causing the column of liquid to move downward.
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 doesn't the liquid in the thermometer move when you turn it upside down?
Because it doesn't.
Why does the alcohol in a thermometer go down when the weather is cold?
As the atoms lose energy (through the cold weather) they lose energy and vibrate less. If you imagine this, as they vibrate less, they don't bump into each other as much and the spaces between the particles decrease. As the spaces get smaller, the whole liquid gets smaller, causing the liquid to "go down".
How a solid changes into a liquid?
for example ice is melted down into a liquid
How could weather changes slow down the effects of global warming?
They can't, as weather changes (or climate changes, actually) are the result of global warming.
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 does the liquid in a thermometer go down before the temperature is taken?
It does not by itself. It must be shaken down. The liquid is mercury, which is very heat-expansive, i.e. it changes its volume noticeably and quickly depending on its temperature. The warmer, the larger the volume. That's why it's used in thermometers. However, thermometers are built so that the mercury does not go down by itself to enable taking precise readings (otherwise, it would fall quickly immediately after the thermometer is removed from the body). So, the thermometer must cool and the contracted but vacuum-stuck mercury must then be shaken down to take another measurement.
Cold weather slows down the process of?
a liquid to flow.
How does the liquid in a thermometer move up and down?
When the liquid in the thermometer gets warmer it expands. This means its volume increases. The only place for the extra volume to go is up the tube, so the level of liquid rises. When the liquid gets colder it contracts (reduces in volume) so it moves back down the tube. See http://www.energyquest.ca.gov/how_it_works/thermometer.html
Computers tracks weather changes?
Yes, they do. All weather changes are collected by the satellites and passed down to the computer systems on earth who record and predict weather changes based on pre-defined algorithms.
