2000 degrees celciuc
about and hour
it would probably take about five minutes for the ice cube to actually melt
That is a function of the temperature of the ice.
Depends on how hot or cold it is outside. Probably never melt at the south pole.

At 70 degrees it would take 24 hours to melt 2000 lbs of ice

At 0 degrees Celsius, water (ice) is at its freezing point so it wouldn't really melt unless it goes above. At 0 degrees Faranheit, water is well below it's freezing point and wouldn't melt.
approximately 40 seconds if it is at room temperature that is 25 degrees c at 298k
About four hours and twenty minutes.
It depends on the composition of the steel as there are many different grades and types of steel.
I'm not sure you understand what the term "melting" means. It only takes one person to melt silver, so long as you have a furnace that can heat it to 1,763 degrees.
If you heat NaCl to 801 degrees C, it will melt and if heated to 1413 degrees C, it will boil. You can definitely melt salt in a Bunsen burner flame in one class period, but heating it to boiling would take some time.
it depends upon the amount and the shape of the ice.
it takes 2 minutes for it to melt
