How Does Running Water Freeze at Mariann Noe blog

How Does Running Water Freeze. It stays liquid at lower ambient temperatures, but it sometimes generates enough heat via friction that the water itself stays above. But the water is constantly moving. In short, running water doesn't stay liquid at lower temperatures. The flowing does not change the freezing point of water, but it can change how difficult it is for the water to actually reach that. Then, a thin layer at the surface starts to freeze while floating on the denser water below. By contrast, in moving water, the entire volume has to cool to 0c before freezing starts. The water at the surface is exchanging heat with the air, so once the air gets below 0 c and the surface water is at 0 c, ice will form. Yes, moving water can freeze at temperatures above 0 degrees celsius, but it will take longer compared to still water. As the water freezes and expands, the kinetic energy exerted by the ice against the pipe actually melts the ice, and just enough will melt.
