Why hasn't mercury been pulled into the sun?
Mercury has not been pulled into the Sun because it is in a stable orbit, where the gravitational pull of the Sun is balanced by Mercury's orbital velocity. This balance keeps Mercury in its current orbit around the Sun.
Why is roman god of speed an appropriate name for the planet mercury?
Mercury, the Roman god of speed, is an appropriate name for the planet because it is the closest planet to the sun and moves rapidly in its orbit. Mercury's swift movement and short orbit period of just 88 days parallel the speedy characteristics associated with the god Mercury.
Why mercury's surface temperature varies so much from day to night?
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.
Why the Mercury-in-glass thermometer first descends and then rise when put in flame?
When placed in a flame, the glass bulb expands rapidly. This increases the volume of the bulb and so the column descends. However, the glass then conducts the heat to the mercury so that it undergoes thermal expansion and the column rises.
Does it take mercury 10 hours to orbit around the sun?
It takes Mercury considerably more time than that to complete an orbit (if Mercury were moving that fast, it would be orbiting around the sun significantly more rapidly than the sun itself spins).Mercury's "year" is approximately 88 Earth days long.
Why was Mercury given this name?
The planet Mercury moves rapidly across the sky. The Greek God Mercury moved rapidly because he was the messenger of the Gods. The one suggested the other so the planet was given the name of the Greek God.
Why is mercury used in thermometres?
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.
Why was Mercury given it's name?
In Greek mythology, Mercury was the messanger of the Gods, moving rapidly from place to place performing his functions. The planet Mercury has been known to people from ancient times and appears to be the most rapidly moving of the planets. Since the planets were named for the gods, the connection with a rapidly moving god caused the planet to be named Mercury.
Why hasn't mercury been pulled into the sun?
Mercury has not been pulled into the Sun because it is in a stable orbit, where the gravitational pull of the Sun is balanced by Mercury's orbital velocity. This balance keeps Mercury in its current orbit around the Sun.
Will aluminum sink or float in mercury?
Aluminium will always float in Mercury. The mass of the Aluminium is irrelevent. If you think of a more common example does it matter how big the piece of wood is as to whether it floats in water? Aluminium floats in Mercury because it is lighter than the same voluime of Mercury just as wood floats on water because it is lighter than same volume of water.
How did mercury get it name?
Mercury got its name from the Roman messenger, Mercury. Mercury was a fast messenger, so Mercury orbits the sun fast.The planet Mercury was named after the Roman god of messengers Mercury.The planet mercury has the most rapid apparent movement in the sky of any astronomical body that looks to the naked eye like a star. Therefore the ancients considered it to be the rapidly moving messenger of the Gods, who was called Mercury by the Romans.
Why is roman god of speed an appropriate name for the planet mercury?
Mercury, the Roman god of speed, is an appropriate name for the planet because it is the closest planet to the sun and moves rapidly in its orbit. Mercury's swift movement and short orbit period of just 88 days parallel the speedy characteristics associated with the god Mercury.
Why mercury's surface temperature varies so much from day to night?
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.
What helps a mercury in glass thermometer to respond quickly to change in temperature?
The thin glass tube and small bulb containing mercury in a mercury-in-glass thermometer allows for quick thermal equilibrium with the surrounding air. This design enables the mercury to rapidly expand or contract in response to temperature changes, causing the height of the mercury column to fluctuate and accurately indicate the temperature.
Why the Mercury-in-glass thermometer first descends and then rise when put in flame?
When placed in a flame, the glass bulb expands rapidly. This increases the volume of the bulb and so the column descends. However, the glass then conducts the heat to the mercury so that it undergoes thermal expansion and the column rises.
What does falling of his mercury mean?
The statement the mercury is falling means that it is getting colder. That's because temperature is often measured by means of a mercury thermometer, in which a column of mercury will get lower as it gets colder (due to contraction).
Does it take mercury 10 hours to orbit around the sun?
It takes Mercury considerably more time than that to complete an orbit (if Mercury were moving that fast, it would be orbiting around the sun significantly more rapidly than the sun itself spins).Mercury's "year" is approximately 88 Earth days long.
