no melting is a physical process
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.
If gold gets hot enough, it will melt. What type of change is this?
Yes, it changes to citrine, another type of quartz. (Citrine is yellow)
metamorphosis
yes because its changing from one form to another form which is physical!!!
When a solid is heated its particles melts and change into liquid

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
type your question here...
Electrons.
A colloid is a type of homogeneous mixture. In this type of mixture, one substance is divided into insoluble particles and dispersed into another substance.
Particles of a liquid: 1) More loosely connected 2) Can collide with each other and most past one another
