No
Could be in the substances themselves. i.e. they are all subject to the same processes but at different temperatures. Thus rock, at normal temperatures, is the equal of being frozen, and rock can be heated to a point where it becomes a gas. Although it is usually a compound, so the gaseous the state of its constituent compounds would be reached at different times. Of existing gases, they can certainly be frozen to a liquid state, I have never heard of one of these becoming a solid, although I believe that some asteral bodies have frozen gases laying on the ground as a sort of frost
At normal pressure, yes.
Frozen ice-cream is ice-cream that has been cooled to the point where it's state is solid. In most normal fridge-freezers it is stored at -5 to -8 degrees celcius. In this state the atoms are tightly packed together, and they vibrate very little. Melted ice-cream has been heated so that it has become a liquid. This means that it has past the melting point of the substance that makes up the ice-cream. In this state, the atoms are a lot more free to move, and not so tightly packed together. If the ice-cream were to be heated further, then the water in the substance would evaporate, leaving behind anything else that made up the ice-cream.
When metal is heated beyond its melting point, it can change its structure permanently due to the atomic rearrangement that occurs. Once the metal cools down, it solidifies in its new structure, which may or may not be its original form depending on the temperature and time of heating.
frozen pizza is a normal pizza, frozen before it is cooked so you can eat it fresh whenever you want to.
That is normal. The fluid expands when heated.That is normal. The fluid expands when heated.
Yes, it's normal frozen water or normal sea water.
No
Yes, it is normal.
nope
Frozen, meaning something is in cased in ice, is different from thaw, meaning it is in the proses of melting, going from frozen state you a normal state. Oh Ya
No, under normal conditions, eating frozen sweet corn would not damage your health.
Be re-warmed to normal body temperature.
Be re-warmed to normal body temperature.
no no no
Smells and looks normal or the easiest way is to cook it and eat it
