2) Which element is used as fuel in nuclear reactors? How many years before we run out of it?
Firlakuza [10]

Answer:Uranium

80 years

To make that nuclear reaction that makes that heat, those uranium pellets are the fuel. And just like any fuel, it gets used up eventually. Your 12-foot-long fuel rod full of those uranium pellet, lasts about six years in a reactor, until the fission process uses that uranium fuel up.

Transuranic wastes, sometimes called TRU, account for most of the radioactive hazard remaining in high-level waste after 1,000 years. Radioactive isotopes eventually decay, or disintegrate, to harmless materials. Some isotopes decay in hours or even minutes, but others decay very slowly.

lesya692 [45]

Answer:

It will reduce

Explanation:

The time it will take to bake the cake will reduce when the temperature is increased by an additional 20°F .

Temperature change has a considerable effect on reaction rates since temperature is directly proportional to the average kinetic energy of reacting particles.

Generally reaction rate varies as temperature directly.

Therefore, the baking time will reduce as temperature increases.
