Is a melting point a chemical change?
A melting point is a physical property. It yields much information in the identification of a compound
Why is melting a physical property of the wax but flammability in a chemical property?
Melting doesn't change the composition of a compound (substance).Burning is a chemical reaction, an oxidation - new compounds are formed.
Is melting physical or a chemical change?
it is a physical changeIce melting is a physical change. Anything changing from a solid to a liquid (or liquid to solid), or from a liquid to gas (or gas to liquid) is a physical change).See the Related Questions for more information.physical change is anything changing from a solid to a liquid
Is melting iron into liquid a chemical change?
No, all changes of state are physical, never chemical. It always can be reversed by temperature change only and no other compound are involved.
How do you cause a physical change?
A physical change does not create a different chemical compound. Grinding a brick into a fine powder is a physical change. Freezing water is a physical change. Melting wax is a physical change.

The test to see what can be done.

What physical change of a solid to a liquid at the melting point?
The physical change of a solid to a liquid at the melting point called melting.
Why is it misleading to identify a solid compound just from a lone melting determination?
Because the melting point can be very similar; also impurities change the value of the melting point.
What causes rocks to change from one type to another?
Rock is continually recycled into new forms of rock by the processes of weathering, erosion and lithification, melting and solidification, or by pressure and/or heat causing recrystallization and changes in mineralization.
What do you call the process in which crystals change in size or composition?
Recrystallization.

What is recrystallization?
Recrystallization is a process in which rocks actually change. It is whereby the crystals of one mineral slowly convert to few but larger crystals of the same mineral with out melting the rock. It is them followed the the process of neomorphism then metasomatism.2.Crystallization is the (natural or artificial) process of formation of solid crystals from a homogeneous solution or melt, or more rarely directly from a gas. This process is often used as a technique to separate a solute from a liquid solution, bringing it into a pure crystalline phase.
