Why can a liquid mercury thermometer only be used between -40 and 360?
The range of -40 to 360 degrees Fahrenheit is within the melting point and boiling point of mercury, ensuring that the mercury remains in liquid form and does not solidify or vaporize. Outside this range, the thermometer would not function accurately as the mercury would either freeze or evaporate.
What time is 1240 am?
Its 40 minutes past 12 in the night, i.e. 40 minutes past midnight
Is Mercury a gas a solid or a liquid?
Known as a liquid but obviously it can be all three. Mercury is a liquid at room temperature, it will solidify if you make cold enough, -40 C and be gas if you make it hot enough, +357 C. It expands and contracts easily in this liquid form, which is why old thermometers used it.
Does Mercury melt easily?
Mercury is liquid at room temperature so it is already "melted" Of course! Mercury is the stuff in thermometers, which (as you know) is liquid. If you've ever broken a thermometer you would have seen the mercury form droplets on the ground (I don't recommend you try this though, it is harmful). Mercury's melting point is in fact -40C. What this means is that any temperature higher than 40-below-freezing is hot enough for mercury to melt.
A sample of liquid mercury is heated from 20 and degC to 40 and degC. Which measurement of the sample will increase during this process?
As the liquid mercury is heated from 20°C to 40°C, its temperature will increase. Consequently, the volume of the mercury will also increase due to thermal expansion, as most liquids expand when heated. However, the mass of the mercury will remain constant throughout this heating process.
Who created the liquid in glass thermometer?
The two most common liquids used in glass thermometers are mercury and alcohol, both of which were created by M. Nature. Alcohol thermometers are, or were, used in extremely cold areas like the Yukon, where the temperature could be expected to drop lower than -40 in the winter (-40 is where mercury freezes, and it is also the only temperature that is exactly the same on both Fahrenheit and Celsius thermometers).
What is the range measured by Mercury thermometer?
Mercury freezes at -38.83 °C (-37.89 °F) so it can only be used at temperatures higher than this.
Does 6 go into 40?
nope it cant because it only goes up to 42 not 40 it goes past 40 :)
You are a metal and a liquid?
You are mercury. Mercury has a low melting point (~-40*C), so under standard conditions it is in a liquid state. It falls under the transition metals group on the periodic table. It's commonly used in thermometers.
What temperature would Celsius and Fahrenheit thermometers register the same reading?
Celsius and Fahrenheit thermometers will read the same temperature at -40 degrees, as -40 degrees Celsius is equal to -40 degrees Fahrenheit.
At what temperatures will the readings on the Fahrenheit and Celsius thermometers be the same?
At -40 degrees.
What is the lowest temperature on a thermometer?
The lowest temperature on a standard mercury thermometer is typically around -40 degrees Celsius or Fahrenheit, depending on the specific model. Some digital thermometers can register even lower temperatures.
Which of the temperature that Fahrenheit and Celsius thermometers would read as the same number?
-40c (apex)
What temperature Fahrenheit and celsius thermometers would read as the same number?
negative 40 degrees
Why can a liquid mercury thermometer only be used between -40 and 360?

Difference between mercury and alcohol?
Mercury is an element, a metal. Alcohol is the name of a familty of organic compounds made up of carbon, oxygen, and hydrogen atoms in various combinations. The only obvious similarity of the two substances is that some alcohols (ethyl alcohol, or ethanol, C2H5OH, for example ) share a common freezing point with mercury of about minus 40 degrees (Celsius or Fahrenheit), making them suitable for use in outdoor thermometers.
What only metal is liquid at room temp?
Mercury is the only common metal that takes the form of liquid at room temperature. There is not "only" one metal at room temperature, depending on how you define room temperature.Metals liquid at room temperature (25 0C)mercuryMetals liquid at temperature 30 - 40 0CFranciumCesiumGalliumRubidiumMercury is sometimes referred to as "quick silver," and its chemical abbreviation, Hg, is derived from the Latin word for it, which means "liquid silver."
