Nuclear energy
AdminWhat is Nuclear Energy? Nuclear energy is the energy released during a nuclear reaction. This reaction can be either fission, which splits atoms to release energy, or fusion, which joins atoms together to create energy. Nuclear energy is used across ...
Why liquids are poor conductors of Heat
Admin
Pure liquids have molecules further apart from each other. Although molecules move about within the liquid, they are slow to pass heat to other regions compared to the free electrons in metals. This is because there are large inter-molecular distances ...
