The definition of sublimation is when a material goes directly from solid to gas phase, without melting first. If the material is liquid and it transforms to gas, that's called evaporation (when it's gradual at any temperature) or boiling (when it all starts to change state at the boiling point). Whenever a solid vaporizes into gas phase, that's called sublimation.
Naphthalene appears to sublime below its melting point because molecules are constantly leaving the surface (it has a high vapour pressure) and these molecules disperse into the air.
that's how the mafia works
About 150 degree Fahrenheit!
15 0C is the temperature for the required conversion.
Hydrogen bonding between the carbonyl oxygen and the hydrogen on the amine group make it more difficult to break up Nylons, thus higher melting temperature than other polymers. this answer was copied from ID2176515335
37.5
Depends on the temperature of the ice.
It is 115- 135 degree of centigrade
when temperature start increaseing from 0 degree, ice start melting
every solid can be dissolved. The melting temperature is 100 degree celsius
It depends on the metal. For example, Iron (Fe) has a melting temperature above 2000 degrees F, while Aluminum (Al) has a melting temperature below 2000 degree F. Moreover, Lead (Pb) has a temperature considerably lower then both Iron and Aluminum.
as you might be knowing that freezing and melting point of ice(water) is same the only difference is that when water freezes it gives out its heat whereas while melting it absorbs the heat . so when the ice is melting its temperature remains zero degree .
The melting point of ice is 1 degree Celsius
this is because iron has a very high melting point and therefore at room temperature it remains as a solid......
-38.8 degree Celsius = 234.35 Kelvin = -37.84 degree Fahrenheit The temperature is about 39 degree below melting point of ice and is pretty cold.
Freezing: 0 Celsius or 32 Fahrenheit, unless the sun is shining on it and the temperature is just below freezing.
At melting point of a substance the supplied heat is utilized to change the state so temperature remains constant till all the material is converted into liquid, this is known asLatent heat of fusion.
1535 degree melting of iron
Most soup cans are not aluminum- they are tin plated steel. While the exact melting point will vary with the alloy used, it is ABOUT 1,350 degrees Celsius. It is MUCH higher than the melting point of aluminum.
