it is a physical change
Physical change,because it separates the petroleum into different products.Such as gasoline and motor oil.
Physical. Distillation simply separates components of a solution, which could be returned to their original state.
chemical change, since the structure of the molecule is broken down into various other components.
Distillation is only a method of separation.
it is a physical change
Distillation is a physical process.
physical change because part changes to a liquid or solid, while another part changes to a gas - however the substance is only changing state, so it would be a physical change
Chemical
A physical change simply alters the shape, size, color and physical state (solid, liquid, gas, plasma state) of a material. Melting ice, boiling water, freezing water, mixing sulphur with iron filings, and even tearing paper will produce physical change. Composition of a substance remains unchanged in case of a physical change.A chemical change involves the breaking of old bonds and the creation of new bonds that hold particles (atoms, molecules) together. In this, a new substance is formed. Rusting of an iron, the formation of white ash of MgO when magnesium wire burns are examples of chemical change.A physical change can be reversed by using physical processes such as evaporation, crystallization, distillation, etc; whereas a chemical change can't be reversed using physical processes.
A refinery processes crude oil into different components such as kerosene, gasoline, diesel, LPG (light petroleum gases), etc. A petrochemical plant is a chemical plant that will use a petroleum based feedstock, such as LPG or other products from a petroleum refinery to produce a chemical product, such as plastics for example.
Physical change does not produce a new substance. Chemical change produces a new substanceIn a chemical change the atoms/molecules are chemically joined together so they are very hard to separate. were as they are easyer to separate in a physical change

The change involved in the distillation of wine is chemical. The original chemical make up of glucose changes: (C6H1206 + Zymase = 2C2H5OH + 2CO2 + Zymase). The change is chemical because the glucose chemically changes into alcohol and carbon dioxide.

Chemical changes take place on the molecular level
it is physical because there is no new matter will produce(( water+ juice dissolved)) just
Physical change doesn't produce a new substance, but a chemical change is a new substance.
distillation of crude oil can produce, asphalt, heating oil, diesel oil.
