Yes, when a thermometer is removed from water, the liquid column falls because it cools down and contracts. The liquid inside the thermometer shrinks as it loses heat, causing the column level to decrease.
Do you notice that, as soon as you take the thermometer out of the water, the level of liquid column begins to fall?

Yes, the liquid column in a thermometer falls when it is taken out of the water. This happens because the thermometer cools down to the surrounding temperature, causing the liquid inside to contract. In the water, the liquid expands due to the heat. Once removed, as the thermometer adjusts to the cooler air temperature, the liquid contracts, leading to a drop in the column level. This reflects the decrease in temperature from the water’s heat.
