Understanding the Basics of Freezing

Freezing occurs when the temperature of a liquid drops below its freeze point. For water, this point is 0°C (32°F) at standard atmospherical pressing. However, the freezing point can vary with different substances and under different conditions. For illustration, seawater frost at a low-toned temperature than pure h2o due to the presence of dissolved salts.

During the freezing process, the molecules of the liquid slow down and stage themselves into a crystalline structure. This summons relinquish warmth, cognize as the latent warmth of fusion. The pace at which a substance freeze reckon on several factors, include the pace of heat removal, the presence of impurities, and the surface area exposed to the frigidity.
