Key ideas 1.3 Thermometer Thermometers Working principle Liquid-in-glass thermometer Length of a liquid column increases with temperature Resistance thermometer Resistance of a metal wire increases with temperature Thermistor thermometer Resistance of a thermistor decreases with temperature

Two common types of liquid-in-glass thermometers: Working principle Rotary thermometer A bimetallic strip bends as temperature increases Two different metal wires joined to form a close loop. The current flowing through the loop increases with the temperature difference between the junctions. Thermocouple thermometer Two common types of liquid-in-glass thermometers: mercury-in-glass thermometer alcohol-in-glass thermometer

Clinical thermometers are used for measuring human body temperature. Mercury Alcohol Range: –39 C to 357 C Range: –115 C to 78 C quick response slow response poisonous non-poisonous Clinical thermometers are used for measuring human body temperature.
