Is matter heavier than energy?
of course it is
What happens when two nuclei that are heavier than iron are fused?
The two nuclei's are lighter than iron then when they are fused together they will release energy. If the two nuclei's are heavier than iron they will absorb energy when fused.
Are bigger thing always heavier than smaller things?
No
Why neutron heavier than proton?
To conserve energy in beta decay.
Massive stars cannot generate energy through iron fusion because?
No energy is gained when fusing iron into heavier elements. Heavier elements have a higher potential energy (nuclear energy) than iron.
Does aluminum always have a greater mass than iron?
not always but I guess it could be heavier than iron if their was a lot more of it.
How is a supernova related to matter found on earth?
A supernova is a star that explodes. Stars about the size of our Sun explode when they run out of "fuel". The fuel they have is Hydrogen which they fuse into Helium and thus convert mass into energy (they shine brightly), Then the Helium and some Hydrogen are fused into heavier elements (Lithium etc) making more energy. All elements heavier than Carbon and lighter than Iron are made in the supernova explosion that comes at the end of the star's "life". Heavier stars will make even heavier elements. The Earth is mostly made of these heavier elements. We are all stardust.
Is there something that is smaller than matter?
Matter is everything that isn't energy. There is nothing other than matter and energy. You can't compare the two. It's like asking, "What's bigger than the universe?"
Is fusing two mercury-202 atoms a way that energy can be released?
No. Basically, if you fuse anything heavier than iron, you will require energy input, rather than releasing energy.
How can you know that an object is matter or not matter?
if it is an object, than it is composed of matter. if it is a form of energy, then it is not concidered matter
Why do rivers deposit heavier sediments first?
Because it requires more energy to transport heavier sediment than lighter sediment. As a river flows it loses energy, and hence begins to drop the heavier sediment. Imagine you had a handful of sand and a handfull of flower. The sand is heavier than the flower, and also larger. If you blow on both of your hands, the flower will be easily blown away, but the sand will be more difficult, because the grains are bigger and heavier, and require more energy to move.The heavier sediments are the first to overcome the power of the moving water with the power of gravity.
How many represent a complete outermost energy level for elements heavier than boron?
14
