How can you tell the difference between physical and chemical properties?
You can tell the difference by knowing that a physical property changes shape and that a chemical property changes the substance.
what is the difference between chemical change and physical changes?
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
What Is the difference between physical changes and chemical change?
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
What is the principal difference between weathering and chemical weathering?
occures when the chemical comosition of the rock changes
Difference between a pysical change and a chemical change?
Chemical change changes the electrons of matter, a physical change does not. Water is water as ice, water and steam, this is a change of state but physically there is no change of water it is a change of the energy content of water.

What is one major difference in a physical change and a chemical change is?
Physical change, changes the appearance or the surface. Chemical change, changes the minerals inside the object. Physical deals with the appearance and the surface. Chemical changes the structure of the minerals inside the object.
How are machanical and chemical weathering different?
Mechanical weathering is a process which physically changes the appearance of a rock or structure. Chemical weathering is a process which changes the chemical composition of a rock or structure.
Difference between chemical and physical change?
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
What is the difference between chemical and chemical technology?
Chemical technology would be the application of these principals in a more practical waymaterials produced by or used in a reaction involving changes in atoms or molecules is called chemical
Can compounds be physically separated into their original substances?
No, they are separated through chemical changes.
