Is a melting point a chemical change?
A melting point is a physical property. It yields much information in the identification of a compound
How do you find a compounds melting point?
One common method to determine a compound's melting point is by using a Melting Point Apparatus, which gradually heats the compound until it changes from a solid to a liquid state. The temperature at which this phase change occurs is recorded as the melting point. It is important to conduct multiple trials to ensure accuracy.
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
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.
How is the melting point of an impure compound expected to change with recrystallization?
The melting point of an impure compound is expected to decrease with recrystallization. This is because impurities disrupt the crystal lattice structure, causing a broader melting point range. Recrystallization removes impurities, resulting in a purer compound with a higher melting point.
How can one determine the melting point of a compound?
To determine the melting point of a compound, one can use a melting point apparatus. The compound is heated gradually until it changes from a solid to a liquid state. The temperature at which this change occurs is recorded as the melting point of the compound.
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.

Why is it misleading to identify a solid compound just from a lone melting determination?
Identifying a compound based solely on its melting point is misleading because different compounds can have the same melting point. Additional tests, such as spectroscopic analysis or chromatography, are required to accurately determine the compound's identity. A single melting point determination is not sufficient as it could lead to a wrong conclusion about the compound present.

What causes rocks to change from one type to another type?
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 physical change of a solid to a liquid at the melting point?
At the melting point, a solid absorbs heat energy and its particles gain enough energy to overcome the forces holding them in a fixed position. This results in the solid changing to a liquid state. The temperature remains constant during this phase change until all the solid has melted.
What is the change of state does melting have?
Melting is the change from a solid to a liquid.
Is a melting popsicle a chemical change?
Melting is a physical change.
