Because you need to measure the temperature of water, not the air.
An aquarium thermometer typically works by measuring the temperature of the water through a sensor inside the tank. The sensor detects the temperature and displays it on a digital screen or analog scale. Some thermometers may have a probe that is submerged in the water to provide an accurate reading.
The temperature of a beaker is typically measured using a thermometer that is placed in the water inside the beaker. The thermometer will provide a reading of the water temperature, which indirectly reflects the temperature of the beaker as well.

When using the ice-point method for calibrating thermometers, you should place the thermometer in a mixture of ice and water, ensuring the thermometer bulb is fully submerged. You then adjust the thermometer until it reads 0 degrees Celsius (32 degrees Fahrenheit), which is the freezing point of water under standard atmospheric conditions. This calibration ensures accurate temperature readings at this reference point.
The thermometer will show the temperature of the pure water being collected, which should be around the normal room temperature. If the water was heated or cooled prior to collection, the thermometer will reflect that temperature instead.
Because you need to measure the temperature of water, not the air.
The bulb of the thermometer must be submerged in the water because that is where the temperature of the water is accurately measured. The bulb is the part of the thermometer that contains the temperature-sensitive material, such as mercury or alcohol, which expands or contracts depending on the temperature of the water. This expansion or contraction is then displayed on the thermometer scale, giving an accurate reading of the water temperature.
The temperature of a pond can be measured using a thermometer specifically designed for aquatic environments. This thermometer can be submerged into the pond water to provide an accurate reading of the temperature. Alternatively, electronic devices such as temperature probes or data loggers may also be used to monitor the temperature of a pond over time.

When a thermometer enters cold water, the temperature reading on the thermometer will decrease as the thermometer adjusts to the temperature of the water. The liquid inside the thermometer will contract and move down the scale, indicating the lower temperature of the cold water.
That depends on how hot the water is in the cup. Use the thermometer to measure it and see.
If surrounding water temperature is lower than the water in the thermometer, heat will transfer from the water in the thermometer to the colder water causing the liquid in the thermometer to drop.
A thermometer is used to measure the temperature of hot water.
When a thermometer is quickly dipped in hot water, it won't do anything. If you leave the thermometer in the hot water, the temperature shown will read higher. The temperature shown will not exceed the temperature of the water.
To measure the temperature of cold water, a digital thermometer or a glass mercury thermometer can be used. Digital thermometers provide quick and accurate readings, while glass thermometers are traditional and can be very precise, though they may take longer to stabilize. For best results, ensure the thermometer is fully submerged in the water without touching the sides of the container.
with a thermometer.
You can measure the temperature of water using a thermometer. Insert the thermometer into the water and wait a few seconds for the reading to stabilize. The temperature displayed on the thermometer is the temperature of the water.
