describe all the three types of heat fusion
Answers
Explanation:
In carbon group element: Crystal structure points, boiling points, and decreasing heat energies associated with fusion (melting), sublimation (change from solid to gas), and vaporization (change from liquid to gas) among these four elements, with increasing atomic number and atomic size, indicate a parallel weakening of the covalent bonds in this type of structure.
In heat: Heat as a form of energy a liquid is called the heat of fusion, and the heat of sublimation is the energy necessary to change a solid directly to a vapour, these changes also taking place under conditions of constant temperature and pressure.
In freezing point
The heat of fusion (see thermal fusion), the heat that must be applied to melt a solid, must be removed from the liquid to freeze it. Some liquids can be supercooled—i.e., cooled below the freezing point—without solid crystals forming. Putting a seed crystal into a supercooled
