This is due to the properties of thermodynamics- a substance expanding and retracting due to changes in heat. When we think of a thermometer, one might visualize a thin glass tube with a colorful liquid in it (that lines up with a certain measurement on the thermometer). WebThe thermometers invented by Fahrenheit that contained alcohol and mercury both rely on the fact that atoms expand as they get warmer. The expansion of mercury’s atoms and those of carbon, hydrogen and oxygen (the elements form a covalent bond to create alcohol) causes each organic chemical to rise within the thermometer tube.
