Pure water freezes at 0 degrees Celsius at 1 atmosphere of pressure. The freezing point of salt water is lower and depends on the concentration of salt.Know More
At sea level, water with no inconsistencies freezes at 0 degrees Celsius. At altitude, where the air pressure is lower than at sea level, the freezing point of water increases slightly.
Salt lowers the freezing point of water so that it won't freeze until the temperature drops below 0 degrees Celsius. The exact temperature needed depends on how much salt is in the water. The higher the concentration of salt, the lower the water's freezing point.Learn more in States of Matter
Effectively, the salt molecules stop some of the water molecules from touching the part of the water that is becoming solid. At 32 degrees Fahrenheit, water molecules enter and leave the freezing state at an equal rate.Full Answer >
Vinegar lowers the freezing point of water from 32 degrees Fahrenheit down to 28 degrees Fahrenheit. When vinegar is added to water, it prevents water from freezing at its normal temperature and keeps it in liquid form.Full Answer >
The freezing point of paradichlorobenzene is 127 degrees Fahrenheit at standard pressure. Paradichlorobenzene is used in agriculture to eradicate mold in soil, kill insects, and repel rodents and other pests. It is used in the home to repel clothes moths and in toilet cleaners.Full Answer >
The freezing point of iron, which is the same as its melting point, is 2800 degrees Fahrenheit. Iron has a boiling point of 5182 degrees Fahrenheit. Iron is a metal that belongs to group 8 on the periodic table.Full Answer >
