Key Definitions
- Temperature: a reliable measure of the hotness or coldness of a body.
- Thermometer: a device used to measure temperature — clinical (body) and laboratory (general-purpose) types.
Clinical Thermometer
- Modern type: digital, battery-powered, heat-sensor based.
- Normal body temperature: 37.0°C (98.6°F) — an average value; individual normal can vary slightly.
- Body temperature usually stays between 35°C and 42°C.
- Armpit readings run 0.5–1°C lower than actual.
- Non-contact/infrared thermometers measure without touching the body.
Laboratory Thermometer
- Range: typically −10°C to 110°C.
- Correct use: vertical, bulb not touching the container, read while immersed, eye level with the liquid column.
- Temperature stays constant while water boils or ice melts.
Temperature Scales
- Celsius (°C), Fahrenheit (°F), Kelvin (K — the SI unit).
- Kelvin = Celsius + 273.15.
- Absolute zero ≈ −273.15°C (0 K).
