None.
When heat is applied to metal: It expands the metal Makes it hotter (Obviously) Makes it more maliable (Bendy) Can change its state to liquid at extreme temperatures.
Ice melts into water, wax melts into liquid, and metal expands when heated.
Well, solids. For example, when you heat up metal is expands and when you freeze it, it contracts
Most substances expand when heated because the heat causes the particles to move more rapidly, increasing the space between them and causing them to take up more volume. This expansion is known as thermal expansion and is a common physical property exhibited by solids, liquids, and gases when exposed to heat.
Water doesn't grow into ice. It goes through a change of state from a liquid to a solid. It expands. Non-living things do not grow. However, if you meant expand then some things do when you apply heat to them (E.g Metal) or change their state (Water to Ice) ~ Josh

melting is a physical change. freezing is also a physical change. the only thing that changed was the state of matter. a chemical change for example is buring, the substance changes to co2 and h2o.
This would be a physical change because there is no change in the chemical make up of the metal and there is no creation of new substances there is simply a change in state for the metal.
state of matter: the mix is turning from a liquid to a solid.
Yes, cutting a bar of sodium metal with a knife is a physical change, not a chemical change. The chemical composition of the sodium metal remains the same before and after cutting. The change is only in the physical state of the metal.
When metal is heated, the kinetic energy of its atoms increases, causing them to vibrate more rapidly. As the temperature rises, the metal expands due to thermal expansion. Eventually, at high enough temperatures, the metal may begin to melt and change its physical state.
The change in state from the liquid to the gas state is called vaporization. There are two types of vaporization, evaporation and boiling. You are describing boiling.
