Why mercury or alcohol is used in thermometers?
टिप्पणी लिखिए
उत्तर
Mostly Alcohol and Mercury are used in thermometers as they remain in liquid form even with a change of temperature in them. A small change in the temperature causes changes in the volume of a liquid. We measure this temperature by measuring the expansion of a liquid in a thermometer.
