Is neptunium man-made?
Is neptunium man-made? Uranium, found in rock, soil and water, undergoes a natural nuclear reaction that results in small amounts of isotopes Np-237 to Np-240. The majority of neptunium, however, is anthropogenic; that is, it is created as a byproduct of reactions in nuclear power plants. Why is it called americium? Americium was first isolated […]
Why does gas pressure increase when more particles are added?
Why does gas pressure increase when more particles are added? Adding more molecules of a gas increases the number of collisions between the molecules and the walls of the container. This raises pressure. By their very nature, gases can be compressed, so if the same gas can be put into a smaller container, it will […]
