The temperature of ice is typically 0°C (32°F) when it melts, while boiling water reaches 100°C (212°F) at sea level. These temperatures represent key reference points in understanding thermal energy and phase changes.
No, a laboratory thermometer is not suitable for measuring body temperature. It is designed for measuring temperatures in liquids and may not provide accurate readings for the human body, which requires specific thermometers.
To measure temperature with a laboratory thermometer, ensure it is clean and dry. Immerse the bulb in the substance, wait for the reading to stabilize, and read the temperature at eye level for accuracy.
The liquid commonly used in clinical thermometers is mercury, known for its uniform expansion with temperature changes. However, due to safety concerns, many modern thermometers now use alcohol-based liquids, often colored for better visibility.
An infrared thermometer consists of a lens to focus infrared radiation, a detector to convert it into an electrical signal, and a display screen to show the temperature reading. It often features a trigger for measurement activation.
A digital clinical thermometer comprises a temperature sensor, a microprocessor for data processing, and a digital display for temperature readings. It often features a flexible probe tip and a battery for portable operation.
A clinical thermometer consists of a glass tube containing a thin column of mercury or colored alcohol, with a bulb at one end. It has calibrated markings for temperature measurement, typically ranging from 35°C to 42°C.
A laboratory thermometer consists of a long glass tube filled with mercury or colored alcohol, featuring a bulb at one end. It has a graduated scale for measuring temperatures typically ranging from -10°C to 110°C.
To convert Celsius to Kelvin, add 273.15 to the Celsius temperature. The formula is: K = °C + 273.15 This conversion reflects the difference in the starting points of the two temperature scales.
