Because it needs to be brought up to the temp of homiostasus for water before it can be heated from that state into a vapor, and you need to extract the engery that was needed to freeze the water also.
in solid the attraction between molecules is high,
when we heat the kinetic energy of molecules increases.
only when molecules become more movable it occurs melting and boiling so it have have higher melting and boiling point
The melting or freezing points are different for different substances. At room temperature your pencil and desk are solid, which means that they are frozen. However, water is a liquid at room temperature and is not solid (frozen) until it's temperature reaches 0 degrees Celsius.
The melting point is the temperature which a material, element or mixture, changes from the solid to a liquid. Therefore, all liquids become solids above the melting point.
Solids become liquids when the temperature reaches melting point, groups of particles start to brake away from each other. This is when the solid starts becoming a liquid. Liquids become solids on cooling, the particles move slower and become a solid.
For metals it has a low melting point compared with iron or vanadium which melt at over 2000 degrees C
Because the other liquids think dew point stinks.
melting point and/or freezing point (they mean the same thing/are the same temperature)
No. The melting and boiling points of liquids vary considerably.
melting point..
Not at all.
The melting point of lead is 327oC, as taken from my periodic table.
Ionic compounds have a higher melting point.
The melting point is the temperature which a material, element or mixture, changes from the solid to a liquid. Therefore, all liquids become solids above the melting point.
the impurities will lower the melting point value.
melting point is 112.8 deg C. which is pretty low when compared to others.
Liquid nitrogen has no melting point. A melting point is the temperature when a solid turns into a liquid. Since liquid nitrogen is already a liquid, it has no melting point. It is already melted, compared to solid nitrogen.
becaus it has a extreemly stable set of valence electrons
I use Petroleum Jelly, (Vaseline) in my wax and it lowers the melting point a bit.
Ionic compounds have a higher melting point.
