● Mercury has been frequently used in thermometers because it remains in liquid form throughout a wide range of temperatures i.e -37.89 degrees Fahrenheit to 674.06 degrees Fahrenheit. Hence statement 1 is correct. ◦ The mercury thermometer was invented by physicist Daniel Gabriel Fahrenheit in Amsterdam. ◦ Mercury has a greater coefficient of thermal expansion than alcohol. ● A thermometer with alcohol is used to measure low temperature because its freezing point is low i.e -117°C. Hence statement 2 is correct. ◦ It is Impossible to measure high temperatures because of it’s low boiling point. ● The thermometer with mercury cannot be used to measure the very low temperature because its freezing point is high i.e -40° C.Hence statement 3 is correct.
