Not much, 1Kg is subcritical.
I litre of water weighs one kilogram on year and would weigh 0.1 kilograms.
Uranium has the greater density. Note that "1 g" is irrelevant - the density of a substance doesn't depend on how much of the substance you take.
You cannot weigh 45 kilograms because a kilogram is a measure of mass, not of weight. If your mass is 45 kilograms, your weight on the surface of the sun would be 12330 newtons.
1 kilogram is equivalent it 1o Newtons (force stemming from gravity).
Kilogram is a unit of mass, not of weight. - Wikipedia lists the mass as 5.6846

To release the same amount of energy as one kilogram of uranium undergoing nuclear fission, approximately 3.6 metric tons of coal would need to be burned. Uranium undergoes much more efficient energy release through fission compared to burning coal.
Lead is not naturally present in pure uranium. Therefore, there should be no lead in 1 kilogram of pure molten uranium. Lead can be found in trace amounts as impurities in uranium ores, but it is removed during the refining process to obtain pure uranium.
False. The amount of energy produced for each kilogram of uranium is significantly higher than the amount of energy from a kilogram of coal. Uranium has a much higher energy density compared to coal, making it a more efficient and powerful source of energy.
Approximately 30,000 kilograms of coal would need to be burned to produce the same amount of energy as is generated by a kilogram of uranium fuel pellet. Uranium fuel has a much higher energy density than coal, making it a more efficient and cleaner source of energy.
One kilogram of uranium yields significantly more energy than one kilogram of coal. Uranium's energy density is much higher due to nuclear fission reactions, making it a more efficient energy source compared to coal, which relies on combustion for energy production.
It would require an immense amount of uranium, far beyond what is accessible on Earth, to detonate the planet. The idea of destroying Earth with uranium or any other material is simply not feasible with current technology.
Approx. 120 $ for 1 kilogram of unrefined oxide U3O8 (July 2011)
approx. 120 US $ for 1 kg of unrefined uranium (exprimed as U3O8)
The cost of uranium varies wildly depending on who is selling it, and who is buying it. If you are looking for black market prices, they will obviously be high. But if you are looking for the low-radioactive uranium in uranyl compounds for pottery, the costs can be very low.
1 kg of 235U = 3 000 t coal
No, both a kilogram of feathers and a kilogram of lead would weigh the same, as they both have a mass of one kilogram. However, the volume of feathers would be much larger than the volume of lead due to their different densities.
