Ice can also sublimate, which means that it changes from solid to vapor directly, without melting.

How can you tell that the melting of ice cube is a physical change?
You could test the resulting liquid by determining its boiling point and melting point. If they are the same as the boiling and melting points for water, then it is probably water and a physical change rather than a chemical change has occurred.
How are melting and evaporating different?
First, melting is the phase change of solid to liquid and evaporation is the phase change of liquid to gas. Second, Evaporation requires more energy than melting. Evaporation, heat of vapoization constant, is 2260 J/g. Melting, the heat of fusion constant, is 334 J/g.
How does the way the water changes from one state to another compare to the way other subtances change?
The energy density is higher than for other materials, and water has an anomalous density change right around the freezing (melting) point.
What kind of bond would form when you combine zinc and zinc?
Well, there aren't many practical ways of doing this other than melting the zinc, but the bonds will always be metallic.
What is the balanced equation for heating potassium chloride?
There is no reaction (decomposition) when KCl is heated, other than the melting of KCl, above its melting point.
Why melting point of diamond is higher than that of silicon carbide?
Diamond is a covalent network solid, and those types of compounds have higher melting points than other types of compound.
Does waters melting point increase when you add salt?
Nope. It decreases. By lowering the melting/freezing point of water, salt (usually in the form of rock salt) can be used to keep roads and other surfaces clear of ice, as it requires lower temperatures than normal to freeze.
What is the difference between an ice cube melting and the polar caps melting?
One is bigger than the other, there is no difference the same thing on a larger scale.
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.
What must the melting point of the mold be compared to the temperature at which glass gets soft and why?
The melting point of the mold must be higher than the melting point of glass, or else it would not be able to hold the soft glass in the correct shape.
What is the science behind melting chocolate?
well it depends on how it will melt faster.. in the hot sun rather in the microwave.. well of course in the microwave. bbut in the microwave rather than melting it above the fire... then it would melt faster in the microwave also... so basically. it will melt fastest in the microwave.
Why would you expect a metamorphic form at a temperature lower than the melting point of a rock?
if rock melts it will form magma, which leads to the formation of igneous rocks
