because that is far the degrees goes on earth. otherwise 200 degrees or over we all as humans will die or be dead. or the Mercury themometer will explode.
A mercury thermometer is used to measure temperature.
It depends on what you want to measure. Kilograms for mass. Centimetres for height. Degrees Celsius for temperature. Hertz for pulse (even though the unit is not made explicit). Millimetres of Mercury for blood pressure. etc.
Liquid
This may appear so from a Solar System perspective. The degrees of inclination range from 3.38 degrees for Mercury to Earth (which has the largest) with 7.55 degrees of inclination from the Sun's equator.
Depends on the density of the fluid (I assume). Gallon is a measure of volume and pounds is a measure of mass. A gallon of water will weigh far less than a gallon of say mercury.
by the mercury in the thermometer
The liquid in a Mercury thermometer is ... Mercury. Mercury is an element which is liquid from -38.83 °C to 356.73 °C, making it useful for measuring temperatures for most of the environments we encounter in person. Below that range, mercury solidifies and we would have to find another liquid to use in a thermometer or find another way to measure temperature (such as a thermocouple). Above that temperature range, mercury starts to boil (unless kept under pressure) so it's not suitable for measuring high temperatures. In theory we could still use a liquid thermometer with something that is liquid at high temperatures, but it gets rather complicated and there are easier and safer ways to measure high temperatures.
Depending on which location your at on Mercury.... But the most extreme temperatures on Mercury range from 427 degrees Celsius (800 degrees Fahrenheit).........
Electronic balance
Approx 295 Celsius degrees.
The boiling point for the element Mercury is 674.1 degrees Fahrenheit. Mercury can also freeze and melt at different temperatures.
There is a huge range of temperatures found on Mercury. It can get very hot, but very low temperatures can also occur. The minimum temperature found on Mercury is about minus 173 degrees Celsius.
The surface of mercury can get as hot as 380 degrees Kelvin, which is 107 degrees C or 224 degrees F.
Thermocouples can measure a wide range of temperatures however accuracy is a common limitation. Thermometers give consistent results however they may become decalibrated easily. Mercury thermometers are extremely accurate but they cannot be used at temperatures below negative 38 degrees Celsius.
There are two main similarities between Mercury and Pluto. One is their smaller sizes, although Pluto is far smaller than Mercury. The other is their extreme distance from the sun. So Mercury is the closest known planet to the sun while Pluto was considered the furthest.
The planet Mercury turns so slowly that any given location experiences 88 days in the blistering light of the Sun. Temperatures on the daylight side can reach 700 K, which is 427°C or 801 °F.
The core of Mercury makes up 42% of the planet itself. Temperatures can range from 100 Kelvin to 700 Kelvin.
