The melting point is the same as the freezing point, usually. The freezing/melting point is usually lowered to a lower temperature by impurities due to the impurities "messing up" the crystal lattice of the solid phase. The crystal lattice cannot form as easily with a lot of garbage present, so it requires a lower temperature to accomplish freezing. Likewise, the polluted crystal lattice will melt easier and thus it will melt at a lower temperature. This is why we put anti-freeze into our car radiators, to keep your engine block from cracking from the freezing of the coolant water during freezing weather. I hope this helps

Gold's freezing point is 1064.58 degrees celsius.\n(This is the melting point and melting points are the same as freezing points.  Water, for example, melts at 0 degrees celsius but also freezes at 0 degrees celsius.)

Depends on the quantity of ice in the water, time you measure it at, etc. All depends on the precise details of the experiment.

The melting point of a crystalline solid is the temperature at which it changes state from solid to liquid. When considered as the temperature of the reverse change from liquid to solid, it is referred to as the freezing point.\n\nFor most substances, melting and freezing points are equal. For example, the melting point and freezing point of the element mercury is 234.32 kelvins (−38.83 °C or −37.89 °F). However, certain substances possess differing solid-liquid transition temperatures. For example, agar melts at 85 °C (185 °F) and solidifies from 32 °C to 40 °C (89.6 °F to 104 °F); this process is known as hysteresis. Certain materials, such as glass, may harden without crystallizing; these are called amorphous solids.\n\nThe melting point of water at 1 atmosphere of pressure is 0 °C (32 °F, 273.15 K), this is also known as the ice point. In the presence of nucleating substances the freezing point of water is the same as the melting point, but in the absence of nucleators water can supercool to −42 °C (−43.6 °F, 231 K) before freezing.\n\nUnlike the boiling point, the melting point is relatively insensitive to pressure. Melting points are often used to characterise organic compounds and to ascertain the purity. The melting point of a pure substance is always higher than the melting point of that substance when a small amount of an impurity is present. The more impurity is present, the lower the melting point. Eventually, a minimum melting point will be reached. The mixing ratio that results in the lowest possible melting point is known as the eutectic point.\n\nThe chemical element with the highest melting point is tungsten, at 3695 K (3422 °C, 6192 °F). The often-cited carbon does not melt at ambient pressure but sublimates at about 4000 K; a liquid phase only exists above pressures of 10 MPa and estimated 4300–4700 K. Tantalum hafnium carbide (Ta4HfC5) is a refractory compound with a very high melting point of 4488 K (4215 °C, 7619 °F).[1] At the other end of the scale, helium does not freeze at all at normal pressure, even at temperatures infinitesimally close to absolute zero; pressures over 20 times normal atmospheric pressure are necessary.\n\n\n--------\n\n\nThe boiling point of a substance is the temperature at which it can change its state from a liquid to a gas throughout the bulk of the liquid at a given pressure. A liquid may change to a gas at temperatures below the boiling point through the process of evaporation. Any change of state from a liquid to a gas at boiling point is considered vaporization. However, evaporation is a surface phenomenon, in which only molecules located near the gas/liquid surface could evaporate. Boiling on the other hand is a bulk process, so at the boiling point molecules anywhere in the liquid may be vaporized, resulting in the formation of vapor bubbles.\n\nA somewhat clearer (and perhaps more useful) definition of boiling point is "the temperature at which the vapor pressure of the liquid equals the pressure of the surroundings."\n\nThe reaction\n\nSomething that should not emembered is that boiling is evidenced by the appearance of bubbles containing vapor from the liquid. [Note: The bubbles that precede real boiling in the pot on the stove are either (formerly) dissolved gas or water vapor forming on the very hot bottom of the pot that will be condensed before it can get to the top of the liquid.] Production of vapor requires energy and thus does not occur without some source of energy. This source can be a hot surface or even the liquid itself. Hot liquid will boil as it rises through the bulk liquid if the pressure of the environment drops to the vapor pressure of the liquid at its temperature. This production of vapor will not quickly stop because the temperature of the liquid will not be reduced by the vaporization thus reducing the vapor pressure.\n\nSaturation temperature and pressure\n\nA saturated liquid or saturated vapor contains as mu

The freezing point drops, by the Clapeyron equation. See the attached reference for details. \n\nThe answer above is dealing with ideal gases, not liquid water.

The freezing point of a solution is always lower than that of the pure solvent.Since coffee creamer or sugar are solute masses in a pure solvent like water the freezing point of the solution is less than 0 deg Celsius

The coldest temperature that anything can reach is –273.15 °C. That is called "absolute zero". On the Kelvin scale, which uses the same divisions as the Celsius scale, it is zero, making the point at which water freezes 273.15 °K. Absolute zero is the point at which all atomic movement ceases, i.e. the atoms no longer move relative to one another.\n\nAny material can be heated or cooled to any temperature, as long as enough energy can be added or removed to do so. Materials left in an environment for long enough will reach the same temperature as their surroundings. This is known as reaching equilibrium with the environment.

A liquid is not frozen, it is liquid. Liquid nitrogen is liquid, you can pour it. Freezing Point @ 1 atm: -346.0°F (-210.0°C, 63oK) puts it in a solid state.

cryogenic freezing takes the object to absolute freezing (i.e. not just cold as in -20°).\n\nAbsolute freezing is -273.15°C (or 0° Kelvin)\n\nAt this temperature atoms completely stop moving and therefore stop aging. Anywhere above this temperature, then atoms still move, even if it is a slight little bit.

About -1.8 degrees C, due to the freezing point depression of the dissolved salt (that's why they salt roads in winter)

The normal freezing temperature for pure water is 0c.  However, as the additives are mixed in the pure water (in this case sugar), there will be a depression in freezing point (means lower than zero).  Ultimately it dependends on the sugar concentration in the water.  For an example, you can add few crystal in water and it will still freeze around 0c (slightly below unless you have accurate thermometer) vs sugary syrup that will require much lower temp.\n\nYou can llok up more of these in any Physical Chemistry book (mine is by author ATKINS) under "Depression in Freezing Point, Elevation in Boiling Point).

The answer to this problem lies in colligative properties.  The salt ice solution will have a lower freezing point because by adding the salt, the solution is going through freezing point depression, which means that the solute is spreading apart the molecules of the solvent, thus requiring a lower temperature to freeze.

No.  The point is always 32 degrees farenheit, assuming pressure at sea level.\n\nThe amount will not affect the freezing point, but other factors, such as pressure, will.

Could be that different chemical compounds freeze at different temperatures.  Water freezes at a lower temperature than 36 degrees but not everything does.  That is also like why you put salt on ice to thaw it, it lowers the freezing point, so it has to be a lot colder before you get ice.
