Chemical Change because it`s Re-arrangement of particles either by rearrangement within complex particles or as a result of breakdown and combination of SLG. i thnk it may help u.

Pumping oil is considered a physical change because it involves a change in state or location of the oil without altering its chemical composition. The oil remains the same substance before and after pumping, only its position or state has changed.
oil
Natural gas, gasoline, fuel oil, coal, and LPG burning are all chemical reactions ( chemical changes ). The reactants ( fuel and oxygen ) react yielding primarily CO2 and H2O., which are different chemical species than the reactants.
No it is a physical change because it can be sewn back together and changed. A chemical change would mean tha it couldn't be undone like burning oil. The oil one would not be able to get back.
Yes, burning fossil fuels (coal, oil and natural gas) releases extra carbon dioxide, a greenhouse gas which is the main cause of global warming and climate change.
It is a chemical change.
No because combustion is a chemical reaction. Anything having to do with burning undergoes chemical change. This creates a new substance therefore creating a chemical change.

You can tell this before an oil change. If you see blue smoke coming out the exhaust your engine is burning oil. If you're oil level is low and you have no oil leak your burning oil.

Burning fuel, which may be coal, wood, fuel oil, etc.
Check it at every oil change or more often if you drive in dusty areas and if you have an older oil burning engine with blowby. Or if you notice higher fuel consumption or decrease in power/performance.
Oil floating on water is not a "change", so asking whether it's a physical change or a chemical one is nonsense. To the extent there's any meaning at all to the question, it's a phenomenon caused by the physical properties of the two materials.
An explosion could occur.
Physical ... it's only a state change. Cool it and it reverts to its old condition.
