alchohol has lower freezing point so it is used in minimum bulb,as it contracts the Mercury bar rises in the minimum bulb..
alcohol can easily measure cold temperatures
These wee steel bars are known as riders, and they mark the travel extent of the Mercury column. They are held in place by a feeble magnet. When the reset button is pushed, it moves the magnet away from the tube, and the riders will settle.
A box plot may be used at a preliminary stage to determine the centre and spread of a set of data. The box [and whiskers] plot measures the central point by the median and the range from the maximum and minimum or the quartile points.
A formula used to determine the minimum threshold of perceived change
The recommended minimum length of an anchor line to be used for an overnight stay is a 5-to-1 ratio in good weather or 7-to-1 in bad weather.
The minimum number of bars on an abacus is nine. An abacus is a calculating tool that was used before the written numeral system came into use. It is still used by merchants and traders in countries in Asia and Africa.
Maximum minimum thermometer
six's maximum and minimum thermometer is used to measure the temperature
i dont no just leave me alone
Because of the freezing point of alcohol, temperatures down to minus 70C can be recorded
One practical method is used by gardeners the Minimum and maximum thermometer
Six's maximum and minimum thermometer is a popularthermometer . Its purpose is to recordthe maximum and minimum temperatures reached since the thermometer was last read. Generally speaking a minimum temperatureoccurs during the night and amaximumduring the day.. It is interesting to note that Six's maximum and minimum thermometers were still being used in 2000 of exactly the samedesign and construction as ones produced over 100 years ago. Gardeners use max-min thermometers in the greenhouse and the garden to check minimum temperatures during the cold months when frost can be a problem and to check the maximum temperature during the daytime.Gardeners use max-min thermometers in the greenhouse and the garden to check minimum temperatures during the cold months when frost can be a problem and to check the maximum temperature during the daytime.
Mercury and alcohol
Yes, it can and you can purchase thermometers which use alcohol.
We still use colored alcohol for our liquid in everyday thermometers.
Temperatures are measured by instruments called thermometers.The instrument usually used to measure air temperature is the maximum-minimum thermometer. It consists of a U shaped tube with bulbs at each end and mercury at the bottom. Air heats or cools the bulbs causing the air inside to expand or contract, therefore pushing or pulling the mercury upwards or downwards.There are 3 types of thermometer: minimum thermometer, maximum thermometer,and the "Six's thermometer" -- these record the temperatures over a period of time.it says in my book that a thermometer measures air temperature
The liquid commonly used in a thermometer is mercury or COLOURED ALCOHOL.
The alcohol that is not ever but ao used ts is ethyl, as it is cheaper than mercury and not toxic
