Unlike fresh water, which freezes at 32 degrees Fahrenheit, sea water freezes at 28.4 degrees Fahrenheit. The 3.6-degree difference in freezing temperature is due to the salt that is found in sea water, making it slightly more difficult to freeze.
Despite its lower freezing temperature, at least 15 percent of the ocean is covered by ice at some point in the year. The average temperature of the ocean is 38.3 degrees Fahrenheit, only 9.9 degrees above freezing. Salinity or saltiness is a major determination factor of the exact freezing temperature. Sea water has a typical salinity of 35 parts per thousand, which makes its freezing temperature lower than that of fresh water.Learn More
Fresh water freezes at 32 degrees Fahrenheit, which is 0 degrees Celsius and 273.15 degrees on the Kelvin scale. Seawater freezes at a slightly lower temperature than fresh water due to its high salt content.Full Answer >
The freezing point of soda is slightly lower than the freezing point of water, which is 32 degrees Fahrenheit. Carbon dioxide is added to soda to give it its fizz, and carbon dioxide lowers the freezing point of water.Full Answer >
Anytime the temperature outside drops below 32 degrees Fahrenheit, the water inside the pipes starts expanding, which may cause the pipes to burst. Pipes or hoses that are located outside, in unheated areas of the house or along exterior walls without sufficient insulation are most likely to freeze and burst.Full Answer >
Saltwater freezes, but it does so at a lower temperature than fresh water. The exact temperature of the freezing point depends on the amount of salt in the water.Full Answer >
