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".

Why do fingertips turn white in cold weather?
Your finger turns the colour white after being in the cold because the blood circulation in your finger slows down to warm up the rest of your body. hence the white color.
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
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.
Why is alcohol used in a minimum thermometer?
Because of the freezing point of alcohol, temperatures down to minus 70C can be recorded
Why does the alcohol level in a thermomtere goes down when it cold?
Because the alcohol is pressed in something cold the molecules making it go down

Why does alcohol in a thermometer get low when cold?
The particles in it slow down and do not bouce as high and fast, so the space between them shrinks. 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".

Why do doctors dip the thermometer in a liquid before use?
There are two reasons why the doctor dips in alcohol before use. The first is that any infections of the previous patient may have does not infect others. The second is that the Mercury level should fall down to below 35 degrees centigrade before use.
