Alcohol in a thermometer rises whenever the temperature of its surrounding increases. As the temperature increases, the heat causes the alcohol to expand ever so slightly, which shows up as an increase of height of the alcohol in the tube of the thermometer.
it does not stick the wall of thermometer it expand regularly
risk of mercury poisoning
risk of Mercury poisoning
what do they use for the liquid in glass ball thermometer
The advantages are:They are cheap.They can be seen clearly as they are in red in color.They are thermomatric liquids.The disadvantages are:They wet the surface.They have less surface tension.They have less density.
Daniel Gabriel Fahrenheit invented the mercury thermometer. Ferdinand II invented a thermometer using alcohol but it was very inaccurate.
u don't have to flick the thermometer to reset the temperature reading when you use an alcohol based thermometer (unlike a mercury thermometer where you have to flick and flick and flick flick flick that thermometer for the mercury to be reset so that you can make an accurate reading) a disadvantage is that the alcohol thermometer is slightly less acurate The biggest advantage is that alcohol is not nearly as toxic as mercury, so that if the thermometer breaks, you won't be poisoned.
Because the alcohol boils at a lower temperature than water.
The heat on the outside of the thermometer transfers to the glass which transfers to the alcohol making the alcohol expand making it rise

Well it won't work below freezing.
it does not stick the wall of thermometer it expand regularly
Mercury and alcohol
in a drunken man
it is alcohol to disinfect the thermometer
because it would turn to ice and alcohol wouldn't
