no melting is a physical process
If gold gets hot enough, it will melt. What type of change is this?
Shifting temperature. If its colder, the harder it will get because the particles will compress together. If its warmer, the substance will liquify (melt) or even turn into gas because the particles move apart from each other.
When ice melts, the water molecules in the ice lattice gain enough thermal energy to break the strong hydrogen bonds holding them in place. The molecules themselves do not change into a different type of particle, they simply transition from a solid state to a liquid state.
metamorphosis
Yes, it changes to citrine, another type of quartz. (Citrine is yellow)
When a solid is heated its particles melts and change into liquid
If gold gets hot enough, it will melt. What type of change is this?
No, this is a physical change. Although you melt the glass, the molecules are not transformed into another type of molecule.

rocks can change from one type of rock to another, or not change at all
chemical change
Yes, rocks can change from one kind to another through processes like metamorphism (changing due to heat and pressure) or weathering (breaking down into smaller particles). The rock cycle illustrates how rocks can continuously change from one type to another in any order.

Conduction is the type of heat transfer where heat energy is carried by particles. It occurs through direct contact between particles, causing them to transfer heat energy from one another.
Electrons.
