What is A change in the matter that does not change its identity?
A physical change does not change the identity of matter.
What are the examlpes of chemical change and physical change?
Examples of chemical changes: * Burning of paper * Rusting of iron Examples of physical reactions: * Melting of ice * Melting of wax
What is a change to a material that does not change its composition?
The kind of change described is referred to as a physical change. Examples of physical changes include, but are not limited to, changing the temperature or state of a substance, changing the shape of a substance, and breaking a substance into smaller pieces. A change that alters a material's composition would be classified as a chemical change.
3 examples of physical changes?
Because there are currently four known states of matter, one change between each of these states yields three different types of state change. One is the change from a solid to a liquid, which we will call "melting." The second is the change from a liquid to a gas, which we call "vaporization." The third is the change from a gas to a plasma. There are terms for these changes in the reverse direction, and sublimation describes the change from a solid to a gas with no intermediate liquid phase.
Is ink drying a physical or a chemical change and what are some examples?
Ink drying is a physical change because it involves the evaporation of the solvent, leaving the pigment behind on the surface of the paper. Some examples of ink drying include ballpoint pens, markers, and printing ink drying on paper.

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.
Is melting pysical or chemical?
Melting is a physical process, not a chemical one. It involves a change in state from a solid to a liquid due to the absorption of heat energy.
What is a non example of chemical changes?
non example of chemical change: one non example is ice. ice is NOT an example of chemical change.
