What does the salt do to the melting point of water?
Salt lowers the melting point of water. The water will have to be at a colder temperature to freeze since the salt inhibits the waters ability to form ice crystals at the normal freezing temperature.
Where are the freezing points in silver?
Usually when talking of metals, the point at which silver transitions between states of solid and liquid is called the melting point rather than the freezing point, because of how high these temperatures usually are. For Silver, this temperature is 1763.2 Fahrenheit, or 961.78 Celcius.
Is freezing chemical or physical property?
I would say that freezing point is a boiling property because there is no scientific evidence to suggest that it is or indeed ever will be a chemical property. Freezing point is a chemical reaction. Therefor this is a debatable question. Different people may have different views. This is mine."Freezing point" is usually termed as "melting point" in scientific circles. Melting point is defined as the temperature at which the solid and liquid phase of a substance coexist at equilibrium under the pressure of their own vapors. Ice and water coexist at equilibrium at temperature of 32 degrees F when only their own vapor pressures are acting upon them. However, the temperature difference at atmospheric pressure is negligible. As you can see, melting point (freezing point) only depends on the physical conditions acting on the substance, therefore, melting point (freezing point) is a physical property. Melting point is effected (lowered) by the addition of other molecules or ions to the substance. This effect is physical because it depends only upon the number of particles (molecules etc) added and no chemical reaction is required.
What is the normal freezing point of water in Kelvin?
273.15K is the melting point of water in kelvin That's not correct; water boils at 100 degrees Celsius, to go from C to K, you add 273 to the Celsius temperature... 100+273 = 373 degrees K
What causes the temperature to go down after adding salt to ice water?
Let's assume a couple things: the ice is colder than 32°F (an acceptable premise) and that adding salt to water lowers its freezing point (a widely-known phenomenon).A property of melting/freezing, as well as of boiling/condensing, is that no further temperature change can occur until all of the substance has changed phase.* If you assume that the water in the cup is uniformly at 32°F when we begin, it will be 32°F until all the ice is gone, then begin warming to room temperature.If you add salt to water while the ice is still melting, you lower the freezing point of the water. This is known as fusion curve depression. The ice begins to melt faster because the liquid is no longer at the freezing point. Since our premise says the ice is colder than freezing, the overall temperature of the water will be less than 32°F as soon as salt is added.* Exceptions - superheated and supercooled substances, which are only possible in strictly controlled conditions
A change of occurs during both freezing and melting?
A change in temperature occurs during both freezing and melting. Freezing and melting are physical changes since the chemical contents of the matter do not change.
What is the state of matter of mercury at freezing temperature?
At mercury's own freezing temperature, the mercury can be either solid or liquid; that is the definition of "freezing temperature".
What temperature can liquids can turn into solids?
It depends since every substance has its melting, boiling and freezing point. ex: water's is 0c or less.
A liquid changes back into a solid by freezing at what point?
The FREEZING POINT ----- which for a pure substance (as opposed to a mixture)is the same thing as the melting point since they are both the point at which the liquid phase of a substance would be in equilibrium with the solid. For a mixture, the two would be different and you would get a freezing point range that started at the freezing point and ended at the melting point
Melting point of Ammonia?
Ammonia does not have a melting point since it exists as a gas at standard temperature and pressure. Ammonia will liquefy at temperatures below -33.34 degrees Celsius under pressure.
What does the salt do to the melting point of water?
Salt lowers the melting point of water. The water will have to be at a colder temperature to freeze since the salt inhibits the waters ability to form ice crystals at the normal freezing temperature.

What is calciums freezing and melting point?
Oh, dude, calcium's freezing point is 842 degrees Celsius, and its melting point is 1,484 degrees Celsius. So, if you're planning on freezing or melting some calcium, you better have some serious heat or chill on hand. Just don't expect it to happen at your average freezer or stovetop temperatures.

What is the temperature at a solid becomes a liquid?
It depends on the element, but the general name is freezing point.
What is he he he temperature?
It's probably -20 degrees F, since you are so freaking freezing you are stuttering your question. ;)
