The presence of impurities in a substance results in a lower melting point due to a process called melting point depression. Melting point depression is the reason why adding salt to frozen streets helps to melt the ice. More »

Graphite has no melting point, and instead turns into gas at 6254 degrees Fahrenheit through the process of sublimation. Graphite is entirely made up of the element carbon. More »

To calculate molar mass by freezing point depression, determine the change in freezing point temperature using the freezing point depression constant, and then evaluate molatility. Once molatility is obtained, use it to ... More »
