Give reasons as to why graphite conducts electricity. Why does cornstarch suspension exhibit properties of both solids and liquids? Why is it inadvisable to use ink pen to draw the origin and solvent lines on the TLC plate? Explain in details why the melting point sample ...
Explain why aqueous solution of sodium chloride conducts electricity where as solid sodium chloride does not. Why is the ionic compound NaCl (table salt) able to dissolve in a glass of the molecular compound water (H_2O)? NaCl does not conduct electricity in solid-state, however, ...
Semiconductor: Semiconductors are objects in which the flow of current is not conserved. Similarly, those objects that allow the flow of current are called conductors. These semiconductors are the intermediates between conductors and insulators regar...
