Different proteins have different melting points.
Amorphous solids have no definite melting point because their particles are arranged randomly. Amorphous solids do not have crystal form or definite melting point.
lower melting points
No
Minerals with higher melting points will crystallize.
Alkali metals have relatively low melting points compared to the other metals. Their exact melting points depend on the element itself. But it would be useful to note that their melting points decreases down group I.
Yes, all metals have definite melting points. Most, under earths atmospheric pressure, have very high (hot) melting points, but mercury is liquid at room temperature. Mercury begins to "melt" from it's solid form at 39 degrees below zero!
Amorphous solids have no definite melting point because their particles are arranged randomly. Amorphous solids do not have crystal form or definite melting point.
lower melting points
No
positive ions have high melting points
Ionic compounds have a higher melting point.
No, they only have freezing points & gaseous points (it where the liquid becomes a gas). Why don' they have melting points? Well take this as an example: If you left your chocolate bar out in the sun it will melt and become a liquid. There for becoming a liquid IS melting, there is no further melting points to an object ounce it becomes a liquid. Substances have melting points. The melting point is the temperature at which a solid becomes a liquid, in other words, the temperature at which it melts.
Minerals with higher melting points will crystallize.
According to RAOULT, when two different metals of different melting points are melted or alloyed there melting points considerably change. So,according to the percentage of impurities, the melting points either increase or decrease.
Ionic compounds have a higher melting point.
Melting and boiling points are different for each compound or element.
Ionic solids are characterized by high melting points.
