What is liquid metallic hydrogen quizlet?
What is liquid metallic hydrogen quizlet?
Liquid metallic hydrogen is a phase of hydrogen which conducts electricity. Only Jupiter. and Saturn contain hydrogen in this form. This form of hydrogen exists only at cool or cold. temperatures, and at extreme pressure.
What are the Maria composed of is this material found elsewhere in the solar system?
Is this material found elsewhere in the solar system? The maria are composed chiefly of basalt. Basalts are also found on Earth, Venus, Mars—and to a much lesser extent—Mercury.
What evidence do we have that Pluto and Charon are made of mixtures of rock and ice?
What evidence do we have that Pluto and Charon are made of mixtures of rock and ice? Spectra show that both bodies have some surface ices and both bodies have a density of 2 grams per cubic centimeter. This diagram shows the orbit of Charon around Pluto to scale with Earth.
What creates metallic hydrogen in the interiors of Jupiter and Saturn and why do we call it metallic?
Inside Jupiter and Saturn, gaseous hydrogen gives way to liquid hydrogen and, deeper down, liquid metallic hydrogen. The temperatures and pressures inside these gas giants cause hydrogen to take on properties more befitting a metal. The form an element takes depends on its pressure and temperature.
What is liquid metallic hydrogen which planets contain this substance what produces this form of hydrogen?
Jupiter
Liquid metallic hydrogen is a phase of hydrogen which conducts electricity. Only Jupiter and Saturn contain hydrogen in this form. This form of hydrogen exists only at cool or cold temperatures, and at extreme pressure. No other planet has enough mass to produce enough pressure.
Why Uranus and Neptune do not contain liquid metallic hydrogen?
These two planets do not have enough hydrogen, or sufficient mass and internal pressure, to squeeze the hydrogen into a metallic state. So there is no internal shell of liquid metallic hydrogen inside Uranus and Neptune.
What are the maria composed of?
Samples of lunar rock and soil brought back by Apollo astronauts proved that the maria are composed of basalt formed from surface lava flows that later congealed. This debris layer, comprising rock fragments of all sizes down to fine dust, is called regolith.
What two structures are found in the moon’s maria and were formed from cooling lava?
1 – Craters formed when rocks from space collided with the moon. 2 – Maria formed when lava flowed out of the moon, filled large craters, and cooled to solid rock.
Why is there no liquid metallic hydrogen zone in the interiors of Uranus or Neptune?
Uranus has little remaining heat of formation. Why is there no liquid metallic hydrogen zone in the interiors of Uranus or Neptune? The pressure is too low for hydrogen to be metallic. The gas giants are Jupiter & Saturn, and the ice giants are Uranus & Neptune.
What is the evidence for a liquid water ocean on Europa and why is this interesting to scientists searching for extraterrestrial life?
What is the evidence for a liquid water ocean on Europa, and why is this interesting to scientists searching for extraterrestrial life? The surface of Europa has blocks of ice that are believed to be collided with one another. Adding a week magnetic field implies the presence of a liquid layer below the surface.
What causes Jupiter and Saturn to have metallic hydrogen in their interiors quizlet?
Jupiter’s intense magnetic field traps high energy particles from the solar wind and forms a radiation belt around the planet. Both Jupiter and Saturn contain liquid metallic hydrogen.
What is liquidliquid metallic hydrogen?
liquid metallic hydrogen – (n.) Hydrogen in a state of semi rigidity that can exist only under conditions of extremely high pressure, as in the interiors of Jupiter and Saturn.
Why is there liquid metallic hydrogen on Jupiter?
When this happens at very high temperatures and low pressures, we call this a plasma — the same stuff as the bulk of the sun or a lightning bolt. But in the depths of Jupiter, the pressures force the hydrogen to behave much differently than a plasma. Instead, it takes on properties more akin to those of a metal. Hence: liquid metallic hydrogen.
What is the EOS of liquid metallic hydrogen?
In Jupiter and Saturn, liquid metallic hydrogen consists of a dense mixture of ionized protons and electrons at temperatures over about 10,000 K. The EOS of liquid metallic hydrogen is understood well theoretically for pressures above about 10 Mbar, but the EOS is not well constrained from 1 to 10 Mbar, the transition region.
What is metallic hydrogen and why does it matter?
This is metallic hydrogen: hydrogen that behaves like a metal. Metallic hydrogen is conductive, and it’s believed to be largely responsible for the dynamo that powers Jupiter’s and Saturn’s magnetic fields. (Whereas on Earth, that dynamo is powered by liquid iron, an actual metal.)
