The naturally occurring radioisotope which is used as the fuel for a nuclear reactor is the Uranium-235. It has been said that one kilogram of Uranium-235 can theoretically male about 20 terajoules of energy when used as a fuel for power plants.
Gravitational potential energy=mass of object x gravitational field strength on earth(9.8 usually rounded to 10) x the height the object is held at
Therefore if two objects were held at the same height, the object with more mass(the heavier object) will fall faster because it's gravitational potential energy is greater than that of the lighter object
Answer:
these material would have very high boiling points
