Why are the temperature ranges on mercury so dramatic?
Because it doesn't have an atmosphere or its atmosphere is very thin
Mercury is a liquid over a wide range of temperature ( -39 to 357 degrees ) so it can be used in a variety of temperature ranges. Secondly it does not stick to the glass tubing of the thermometer so when the temperature falls ( i.e. after the reading is taken) all the mercury falls back into the reservoir. This ensures the accuracy of the mercury thermometer.
There are no greenhouse gases on Mercury. Just a very thin atmosphere of helium and hydrogen. So it has no greenhouse effect. Its surface ranges in temperature from -270°F to 800°F (-168°C to 427°C).
One of the reasons is that mercury is a liquid at room temperature so we can use Mercury in a thermometer in a room to see the temperature of something.
to see what is the temperature The mercury expands or contracts depending on the temperature so its height against the scale on the thermometer tells you the temperature.
To measure the temperature calibrated in the thermometer. Mercury as a liquid reacts well to temperature changes. It expands as it gets warmer, so thermometers measure the rise of the mercury to measure temperature.
Mercury is a liquid at room temperature; this made it a useful substance in thermometers. As the mercury heated up, it expanded; this indicated the temperature of the surroundings. Similarly, the colder it got, the more the mercury 'shrunk' so it indicated the low temperature.
Mercury is toxic, so you have to be careful not to spill it Mercury changes volume/density with temperature (which mercury thermometers rely on) so you have to correct for this when reading them.
Like most other substances, mercury takes up the temperature of its surroundings, so its average temperature must be room temperature, unless you put it into somewhere hot or somewhere cold.
the liquid has to be at room temperature.
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.
The boiling point of mercury is 356,73 0C, a temperature not so high.
Mercury is a liquid at room temperature. When it heats up it expands, and when it cools it contracts. This is the re line that you see, and shows the temperature accurately. You usually have mercury because it is a liquid at room temperature, so it can go up and down freely. Hope this helps :)
Mercury's melting point is close to the room temperature, so it is a good indicator of temperature around room temperature.
Mercury based thermometers have a column of mercury which visibly rises or falls, according to the temperature. So it does fall, when it gets colder.
It has a reaction to temperature, so it'd be perfect for measuring it!
because the temperature hasn't reached the boiling point of the surface that makes up mercury.
Mercury at normal temperature and pressure is a liquid and will not hold a magnetic field - so it cannot be magnetized.
Because the temperature on Neptune is so extreme, it is unlikely to be able to support life. The temperature on the planet ranges from -270 to -380 degrees.
Mercury will not only irritate your skin. Mercury evaporates, and can be inhailed without knowig. so it is not a good idea to expose Mercury since it is toxic and evaporates at room temperature.
Once it was thought that Mercury does not rotate. We now know that Mercury does rotate, and it takes 58.6 of our days to make one revolution. So in answer to your question every part of Mercury gets very cold and also very hot. The temperature on the surface ranges from -170o C to 430oC (-270oF to 800oF) And the side that faces away from the Sun gets so cold because there is no atmosphere… Read More
Would have it be possible to make mercury thermometers if expansion of glass is greater than the expansion of mercury?
Suppose so, but the mercury would fall, instead of rising with temperature increase.
The main reason is that Mercury has almost no atmosphere which would hold the heat in. So the temperature on the side which is facing away from the Sun can plummet.
The night side of Mercury is not receiving any direct sunlight. Because Mercury is so close to the sun, the day side of Mercury has a significant increase in heat.
Jupiter's temperature ranges from 112K (-161C or -258F) to 165K (-108C or -162F) so it is very very very very much colder than Earth.
The answer is: when it is kept so the mercury level in the tube increases showing the temperature
Mercury; ♣ Mercury has a certain Melting temperature, so that if you measured a certain amount times the heat that it gives out to produce a melted version of itself, therefor you can figure out the temperature of air :3 Much Love, Ryan Nash x
Mercury. So close to the Sun, it bakes in its long daytime, but having no appreciable atmospere to spread the heat, loses it to space during the night. Earth's Moon, and indeed, all airless worlds, also display dramatic temperature shifts, but Mercury's got the hottest seat in the house, so to speak.
1) Mercury takes about 58.6 Earth days to rotate, so the daytime lasts a long time and so does the night. 2) Mercury has no significant atmosphere to carry heat around the planet.
Mercury metal is a liquid at room temperature. By visually determining the physical state of a substance does not produce a new substance. So if the mercury is a liquid that means it underwent a physical change because nothing was added.
The element mercury is a liquid at room temperature not a solid. So it would be difficult to use is as an ornament unless you put the mercury in something. The freezing point of mercury is approximately -38oF so you couldn't really use it as a solid anyway. Yes, mercury is toxic, very toxic, so you shouldn't really handle the stuff at all.
Mercury is very hot in the "daytime", but very cold during the "nights". So it's not possible to give a meaningful answer really. Typical maximum temperature: 430 degrees Celsius. Typical minimum temperature: Minus 170 degrees Celsius.
Whole July is winter in Uruguay so the temperature ranges from 0° C to 15° approximately.
Brazil's temperature ranges from 77 Fahrenheit to 104 Fahrenheit. So there you have it. That is how much heat Brazil gets.
Mercury expands as it cools. Mercury is placed within the bulb at the lower end of a glass tube so that, as the temperature decreases, the mercury may expand within the tube at a regular rate to make judging the temperature possible. Edit By Rouefever: Mercury expands as it is heated, not cooled, like many other substances. Cooling Mercury will make it contract, and then solidify (or freeze).
Because the temperature is frome -279 F to 800 F so we could not live there.
Mercury has almost no atmosphere and so there is nothing to hold the Solar heat in. As a result the temperature drops during Mercurial nights. The polar regions of Mercury get very little direct sunlight and so they are always below 180 K.
A thermometer having mercury is placed in direct sunlight.Will it read the temperature of air or of sun or of something else?
The actual temperature of the sun is high enough to vaporize mercury, so a mercury thermometer could not measure it. The thermometer would just explode at that temperature. If a thermometer is placed in direct sunlight what you will get is a somewhat higher reading than that of the ambient air temperature. It could be described as a combined effect of the air temperature and the temperature of the sun, but it is much closer… Read More
Young's Modulus only holds for solid substances which are elastic. Mercury is a liquid at room temperature so it doesn't have an elastic or young modulus.
It is a metal and is malleable. It can only be hammered in solid state, so it would have to be at a temperature below its melting point, definitely not at room temperature-pressure.
different bacteria have different temperature ranges many however are adapted to the temperature of 37 degrees Celsius (core temperature of the human body) so for those bacteria anything above 45 to 50 will usually kill them
Mercury was used in old thermometers because mercury expands when it reaches a certain temperature, so it was a really good "gauge". Now, they stopped making thermometers with mercury as the liquid since it was very poisonous. i hope you liked the answer!
it lives out of the semen tank up to 15 minutes because of the dramatic temperature drop. so be quick with your transfers!!!
It is further away from the Sun, so the less heat reaches it.
The temperature of boiling water is just 1000C whereas the temperature of fire ranges from 5000C to 15000C. As the sensation of heat depends on relative temperature so fire is hotter than boiling water.
Yes, a body temperature of 98.4 is considered normal. Even though a body temperature of 98.6 is generally accepted as the normal body temperature, there are studies that show that there are wide ranges of normal body temperatures, so in this case, 98.4 is a normal body temperature.
Melting (or freezing point) of mercury metal is -38.83 °C, -37.89 °F, 234.32 K. So it is fluid at room temperature, the only metal element!
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… Read More
Mercury has such a large tempreture variation because it is so close to the Sun, and when it is not facing it, there is no immense heat source on that side, so it is very cold. From, Legit Answers
To hold the mercury so you have time to read the patient's temperature.
even though mercury is a liquid at room temperature it is a metal so because of its metallic bonding its structure is more compact than water. Water is a simple molecular compound and its particles are not as compact as mercury.
