it expands at constant rate and has got high boiling point.
Mercury gives you AIDS
Using a thermometer we can measure the temperature.
Daniel Gabriel Fahrenheit invented the mercury thermometer. Ferdinand II invented a thermometer using alcohol but it was very inaccurate.
If using a mercury thermometer - about a minute. A digital thermometer - a few seconds.
It has a reaction to temperature, so it'd be perfect for measuring it!
it can be easily seen it gets hot quickly it expands fast.. this is the advantage of mercury in thermometers..
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.
to tell old people that have a mercury thermometer what the temperature is
A mercury thermometer is used to measure temperature.
It generally made using fluid which expand or contract linearly with temperature such as mercury, water or alcohol. Electronic thermometer use the relation of thermal property effect electrical conduction difference to measure temperature.
A clinical thermometer will offer more precise calibrated readings than a mercury thermometer. The range of measurable temperature differs between a clinical and a mercury thermometer with the mercury thermometer having the wider range.
don't break it. If you do open the windows.
