Why Iodine melting point is above room temperature?
Iodine melting point is above room temperature because its vapor pressure is less than one atmosphere.
How can you tell what the melting and boiling points of water are?
That's physical properties, is it a chunk that you can lift up then its a solid, if it can be poured it's either a liquid or a solid ground into grains.
How aluminum melts at 460 degrees in galvanizing zinc pot although its melting point is 660?
formation of low melting point solutionsAll metal melting point in alloy form with other metal is vary according to its portion and always less than its pure condition. Please see the Zn-Al phase diagram. You can find that when the Aluminum portion in the zinc bath is less than 10%, the Zn-AL alloy melting point is less that 450 C.
Is The melting temperature of an alloy is generally lower than its constiuants?
The melting temperature of an alloy is generally lower than the melting temperature of the highest melting temperature of all of its constituents. The eutectic melting temperature is the lowest melting temperature of an alloy system and is in fact sort of defined by that optimal set of percentages of those constituents. The next obvious question is whether there are calculation methods or approximations to determine the melting range of less than "eutectic" percentages.
What happens at the melting point of an object?
At the melting point of an object, it transitions from a solid to a liquid state by absorbing heat energy. The temperature remains constant during the phase change as the solid absorbs energy to break intermolecular bonds and rearrange into a less structured form.
Why Iodine melting point is above room temperature?
Iodine melting point is above room temperature because its vapor pressure is less than one atmosphere.
When the thermal energy of a material decreases?
When the thermal energy of a material decreases, the particles within the material have less kinetic energy, causing them to move more slowly. This can lead to a decrease in temperature and possibly a change in state if it reaches the material's melting or boiling point.
Why expansion of rock is important in the formation of magma?
The melting temperature of materials is affected by the pressure they are under. So when "rock" in the Earth's mantle experiences a decrease in confining pressure, not only does it expand, it's melting temperature drops. If the melting temperature of the material drops below the background (also known as the in-situ) temperature, then melting will occur and in this case magma will form.This typically occurs in the earth where hot upwelling mantle material experiences a decrease in confining pressure (as there is less and less overlying material as it rises) which ultimately causes adiabatic or decompression melting.

When are oil baths and water baths used respectively for melting point determination?
Oil baths are typically used for high-temperature melting point determinations, where the sample needs to be heated to a temperature above the boiling point of water. Water baths, on the other hand, are used for lower temperature melting point determinations, as water has a lower boiling point compared to oil.
Is it true that it takes a lot of heat to melt a substance with a low melting point?
See the expert answer above for a specific answer to the question. However, if you mean 'what is a low melting point' then it means that the temperature at which the substance becomes a liquid is reasonably easy to get to, so you have to provide less heat to get to the melting point than you would if it were high.
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.
Implication of sharp melting point?
When we heat up a crystalline solid so it starts melting.During melting the temprature does not rises until or unless the whole solid is changed into liquid.after changing into liquid it will start increasing temprature.
