Document Summary

When this radiation strikes objects, the energy is absorbed and then re-emitted in the form of longer-wavelength infra-red radiation that does not pass through glass as readily. Hence heat becomes trapped and builds up in an enclosed structure with high internal heat capacity and glass surfaces that face the sun. Nuclear fusion: https://www. britannica. com/science/nuclear-fusion, process by which nuclear reactions between light elements form heavier elements (up to iron), hydroge(cid:374) (cid:894)h(cid:895) (cid:862)(cid:271)ur(cid:374)i(cid:374)g(cid:863) i(cid:374)itiates the fusio(cid:374) e(cid:374)ergy sour(cid:272)e of stars a(cid:374)d leads to the for(cid:373)atio(cid:374) of heliu(cid:373) (he). Generation of fusion energy for practical use also relies on fusion reactions between the lightest elements that burn to form helium. The binding energy of the nucleus is a measure of the efficiency with which its constituent nucleons are bound together. Take, for example, an element with z protons and n neutrons in its nucleus.
