The "Face with Thermometer" emoji depicts a face with a thermometer inserted into the mouth, which is used to take a person's temperature. The thermometer is typically shown as a silver or white device with a bulb at one end, which contains mercury or digital sensors, and a numerical display at the other end that shows the temperature reading.
This emoji is commonly used to represent a person who is feeling ill or has a fever, as the thermometer suggests that the person is taking their temperature to monitor their health. It can also be used to indicate that someone is feeling hot or feverish, or to express concern for someone who is unwell.
