Why does the level of mercury change when it is brought in contact with another object?
When mercury comes in contact with another object, such as a container or surface, its level might appear to change due to adhesion and cohesion forces affecting how the mercury interacts with the material of the object. These forces can cause the mercury to spread out or stick to the surface, leading to a change in its apparent level.
Green light emitted by excited mercury vapor corresponds to a particular energy transition in the mercury atom a more energetic transition might emit?
A more energetic transition in the mercury atom might emit blue light, as it corresponds to a higher energy level jump compared to the green light transition. This transition involves the emission of photons with higher energy values than those emitted during the green light transition.
Is mercury red in thermometers?
The planet Mercury is grey, similar in colour and general appearance to our moon. Red Mercury is a chemical made of Iodine and Mercury. It was used as a medicine a long time ago before people realised it was actually poisonous. It is either in the form Mercury(I) iodide or Mercury(II) iodide.
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.
How does a thermomether works?
A mercury thermometer (like the kind a medic might use) is a thin glass tube filled with the metallic element mercury, which is a liquid. The rate at which mercury expands with heat is known and happens at a constant rate, so the movement of the mercury column up and down the tube can be read off at a scale on the side. Because mercury is relatively dense, it isn't affected too much by changes in atmospheric pressure.
What will happen if mercury lamp is used instead of sodium lamp in plane diffraction grating exp?
Using a mercury lamp instead of a sodium lamp in a plane diffraction grating experiment might result in a different wavelength of light being emitted. This would affect the interference pattern observed on the screen, leading to a shift in the position of the fringes. Additionally, the intensity of the light and the overall visibility of the interference pattern might also be altered.
What unreactive metal is also a liquid?
i think it might be ----------sodium its Mercury. i did this in science.
How do you describe mercury's atmosphere?
Mercury's atmosphere is very thin, composed mostly of oxygen, sodium, hydrogen, helium, and potassium. It is not thick enough to support weather patterns, resulting in extreme temperature variations between the day and night sides of the planet.
Is there mercury in a computer?
Older computers might have mercury, but most modern computers are Mercury-Free.
Does Mercury have cloud conditions that might exist?
No, there are no cloud conditions in Mercury
Does sodium hurt your body?
sodium is salt and salt does not hurt your body. You might get sick if you have alot.
What are object attributes called that helps them distinguish them from other variables you might use?
Fields
Does mercury have any natural resources?
Possibly...... it might!
In what applications might businesses find it useful to distinguish between a human and a computer?
repairing mechanicals
Why would we not expect magnetic fields on the moon or mercury?
You might, but that would be wrong! Mercury has a strong magnetic field.
How might the quantity of sodium affect your health?
Too much of sodium can cause high blood pressure and other health conditions.
Does Mercury have air and water?
So far, observations of Mercury from ground-based observers and the Mariner 10 spacecraft have not shown evidence of a significant atmosphere compared to other planets. Mariner 10 did observe a tiny amount of helium 1000 km above the surface, but this is probably caused by the solar wind and the breakdown of Mercury's crust. Sodium, potassium and oxygen have also been detected in Mercury's very weak atmosphere, but these elements can be lost when they react with the Sun and Mercury's magnetic field.
