Answer:
Use of mercury or alcohol in thermometers.
Explanation:
The application of the idea of liquid expansion in daily life applies in liquid thermometers.
Mercury or alcohol in the thermometer tube moves in only one direction when heat is increased.
When the heat is decreased, the liquid moves uniformly back.
When a doctor or a nurse places it usually under the armpit, the body temperature leads to the movement of the liquid.
The medical specialist then reads your body temperature from the calibrations on it.
