The melting point of a solid determined experimentally comes out to be 160 C but its melting point given in standard textbooks is 150 C. Predict the nature of the solid.
Answers
The melting point of the solid is actually defined as the heat at that a solid become liquid.
The melting point of solid actually indicates the overall strength of force of the attraction between the solid particles.
On the increasing the temperature of solid, the molecules of solid absorb energy in a form of heat.
Answer:
The solid is impure.
Explanation:
If the melting point of the solid has a large difference of over 10 C then there must be impurities present in the sample of solid taken.
Impurities in a solid cause a melting point depression because the impurity disrupts the crystal lattice energies. If the impurity present stabilizes the solid by say hydrogen bonding, then the impurity causes the melting point of the impure solid to increase instead of usually decreasing.
Thus the melting point of impure solid determined experimentally comes out to be 160 C but its melting point given in standard textbooks is 150 C for pure solid.
