Why thermameter not started with zero?
Probably a cheap one
Who invented the Mercury thermameter?
A mercury-in-glass thermometer, invented by German physicist Daniel Gabriel Fahrenheit, is a thermometer consisting of mercury in a glass tube. Calibrated marks on the tube allow the temperature to be read by the length of the mercury within the tube, which varies according to the heat given to it. To increase the sensitivity, there is usually a bulb of mercury at the end of the thermometer which contains most of the mercury; expansion and contraction of this volume of mercury is then amplified in the much narrower bore of the tube. The space above the mercury may be filled with nitrogen or it may be less than atmospheric pressure, which is normally known as a vacuum.

What is the weakness of mercury?
Mercury is an element and is very poisonous. It is not used as a drug.
Before mercury what was used to fill thermometers?
Water was initially used and later on alcohol was used.
What chemical element is used in thermometers?
the element used in termometers is Mercury.
Why is mercury used in thermometres?
Mercury thermometres aren't used much, because the mercury inside is poisones, But the reason that mercury used to be used is because Mercury expands rapidly, conserning the temperature e.g. if it gets hotter, the Mercury expands, so there is more of it. So, when you're measuring the tempurature, you're actually measuring how much mercury is there, therefore telling you what the temperature.
