The reading is not accurate if it is not in the liquid that you are measuring. Once you take it out, the temperature will be measuring the air.
A thermometer should be used to measure the temperature of liquid. Digital thermometers are more accurate and quicker to read than traditional mercury thermometers. Make sure to choose a thermometer that is suitable for measuring liquid temperatures specifically.
The liquid in a thermometer should be a good conductor of heat so it can quickly and accurately reflect changes in temperature. Good conductivity ensures that the liquid expands or contracts rapidly with changes in temperature, allowing for precise temperature readings.
One thermometric property that is required is that it must vary linearly with temperature. In liquid-in-glass thermometers, the length of the liquid thread is often used to determine temperature. Thus when temperature increases, the liquid must expand uniformly with temperature, so that it can be used to measure temperature accurately.
An ideal thermometer should have a narrow, uniform tube with a bulb at one end to hold the temperature-sensitive liquid. This shape allows for easy reading of the temperature, as the liquid expands and contracts uniformly with temperature changes. The narrow tube also allows for quick response to changes in temperature.
The level of mercury changes in a thermometer when it comes in contact with another object because the temperature of the object affects the temperature of the mercury. Heat transfers between the object and the mercury, causing the mercury to expand or contract, which in turn changes its level in the thermometer.

A digital probe thermometer with a long metal stem is ideal for measuring the temperature of liquids. This type of thermometer provides accurate readings and is easy to use for liquids such as soups, sauces, and beverages. It is important to ensure that the thermometer is immersed in the liquid but not touching the bottom of the container to get an accurate reading.

Thermometric liquid is the liquid found in the thermometer that help in the up and down movement of the temperature.

It is important not to let the thermometer rest on the bottom of the beaker because the bottom can be heated unevenly leading to inaccurate temperature readings. Placing the thermometer in the liquid away from the bottom ensures a more accurate measurement of the liquid's temperature.

Heat transfers between the object and the mercury, causing the mercury to expand or contract, which in turn changes its level in the thermometer.
An ear thermometer measures temperature by detecting the infrared heat emitted by the eardrum and surrounding tissue. The eardrum shares blood supply with the hypothalamus in the brain, which regulates body temperature. By measuring this infrared heat, the ear thermometer provides an accurate estimation of core body temperature.
Hold it by the top or use a clamp. But make sure before you take the temperature you stir the liquid around in the beaker first and that you do not let it touch the bottom of the beaker as the glass will be hotter than your liquid.
This is called the meniscus. It occurs because of surface tension between the liquid and the walls of the thermometer. When measuring water, you should read the temperature at the bottom of the meniscus for an accurate measurement.
use red coclored top and throw the probe in the trash can when done
