How long does it take for a 1 km sphere of molten iron to solidify?

To answer the question would require knowledge of several variables that are not specified in the question - to wit:
Is "1 km" the diameter, radius, or circumference of the sphere?
What is the initial temperature of the sphere?
Is the sphere in contact with other matter or is it in a vacuum?
Is the sphere under pressure?
Does evaporation have to be accounted for?
If it is in contact with some other solid, liquid, gas, plasma, etc - what are the physical properties of the material(s) it is in contact with?
Is it radiating to a black body?
Is there any source of energy radiating back to the sphere?
Is the sphere in motion or stationary?
Is the sphere subject to any external fields such as magnetic fields?
I'm sure we could identify even more unspecified variables that would impact the answer, but the point is that the question cannot be answered without more information.

How long does it take for a nutrient agar solution to solidify?
at least an hour
How long was the surface of the earth molten?
The earth was in molten state for approximately 0.8-1 billion years.
What is the earth made up of molten rock or magma?
Molten rock IS magma. Unless you are talking about lava, which is magma without its gaseous content. But lava is not molten for long.
What is the length in degrees of the largest constellation on the celestial sphere?
The largest constellation on the celestial sphere is Hydra the Sea Serpent and it is 100° long.
Is iron a heterogeneous mixture?
No, Iron is a homogeneous mixture as long as the iron is pure
How long will it take to freeze molten gold?
Freezing molten gold depends on several factors, including its initial temperature and quantity. Typically, gold freezes at around 1,948 degrees Fahrenheit (1,064 degrees Celsius). The time required varies, but in a controlled environment, it may take a few minutes to solidify smaller amounts, while larger quantities could take longer, possibly up to an hour or more. The use of specialized equipment and cooling techniques can expedite the process.
What is inside of all of the planets?
Different for each planet. Earth has a core of molten iron and rock. The Moon appears to be solid to the core, having cooled a long time ago. Venus is probably still molten at the core; heck the SURFACE is nearly molten. Mars is smaller and further away, so may have a small molten core or may be solid iron and rock. The gas giant planets may have small rocky cores, or may be gasses compressed to metallic solids by the immense pressure. We will have to do more studies to find out.
What do scientist believe causes earths magnetic field?
The center core of the earth is solid iron surrounded by molten iron. The center is solid due to the great pressure and the spinning mass of molten iron around the solid iron core creates the electrodynamic effect that causes Earths magnetism. Our moon has little or no magnetic field because its core has long since cooled.

Why is zinc important in the production of materials made from iron?
Due to the fact that the zinc and chromium are corrosion resistant,they ll be a coat to protect the materials made from iron,which ll rust after long time used. So,when the iron is dipped in molten zinc,the process is called galvanizing. Thanks.by the way,my english is not my mother tongue.

What was the long term effect of prohibition?
It helped solidify an enduring antipathy toward alcohol beverages.
Is Earth's moon made of molten rock?
No. The molten rock which once constituted the moon was long ago solidified from cooling into igneous rock.
Why do scientis think Earths core contains iron?
Because "molten iron, moving very fast, does in fact produce a magnetic field". Even if that iron isn't molten moving a solid conductor, such as copper, fast will still produce a magnetic field. Crude electromagnet experiments, such as those spun by hand, are evidence of that fact. If the Earth's outer core was "dead" (solidified) as it is on the Moon, and Mars (to a lesser degree), we wouldn't have that field and the atmosphere would have been long ago fried away by the solar winds.
Can you cover the surface of a sphere?
as long as you have enough play-dough in your special bucket to keep the sphere nice and snuggly warm...
Can lead burn through leather?
I presume you mean molten lead. It would depend on how thick the leather is and how long the molten lead is in contact, but it could happen.
