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".

You are planning to go to a very cold place where the night temperature drops to minus 50 deg c which thermometer will you take with you- mercury or alcohol and why?
i think mercury because we never use alcohol in thermometer
Can mercury and alcohol mixed to become a thermometer?
Mercury and alcohol are not the thermometers but the liquids found in the thermometer they have different properties that make them uniqe for example alcohol is safe while mercury is poisonous,alcohol does not expand uniformly but has great expansion while mercury expands uniformly and has low expansion,alcohol is cheap while mercury is expensive,alcohol wets the glass while mercury does not.so alcohol can not combine to form a thermometer simply because they are the liquids found in it and not the thermometer itself.
Uses of alcohol thermometer?
An alcohol thermometer is a liquid-in-glass thermometer which uses ethyl alcohol to gauge temperatures. The alcohol rises and falls as it contracts or expands when a change in temperature occurs.
Why does alcohol in a thermometer rise?
Alcohol in a thermometer rises whenever the temperature of its surrounding increases. As the temperature increases, the heat causes the alcohol to expand ever so slightly, which shows up as an increase of height of the alcohol in the tube of the thermometer.
Why does a thermometer have alcohol inside it?
it does not stick the wall of thermometer it expand regularly
What is the use of alcohol thermometers?
alcohol thermometer is used to measure very low temperature.i.e.-112*c
What are the different type of thermometer?
There are 2 types I'm aware of. They are Mercury and Alcohol. Alcohol is used in very cold temperatures as it does not freeze.
When a cold alcohol thermometer is placed in a hot liquid, the column of alcohol goes downslightly before going up. Explain why?
because

Why is rubbing alcohol a good liquid to use in a simple thermometer?
Rubbing alcohol is a good liquid to use in a simple thermometer because it expands when heat ia added to it. When cold temperatures are added to it, it regroupes.

What instrument measures hot or cold air?
a thermometer
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".
What is a Low-temperature thermometer?
what is the name of a thermometer which can measure low temperatures
What does alcohol in a thermometer rise in a result of?
The heat on the outside of the thermometer transfers to the glass which transfers to the alcohol making the alcohol expand making it rise
Why does alcohol in a thermometer rise?
Alcohol in a thermometer rises whenever the temperature of its surrounding increases. As the temperature increases, the heat causes the alcohol to expand ever so slightly, which shows up as an increase of height of the alcohol in the tube of the thermometer.
