Yes
To change the oil and oil filter in a 2000 Saturn LS, first, drive the car for a few minutes to warm up the oil. Then, locate the oil drain plug under the engine and drain the oil into a pan. Next, remove the old oil filter and replace it with a new one. Finally, refill the engine with the correct amount and type of oil as specified in the owner's manual.
Water condensation on a cold surface and oil in a pan when cooking can form droplets.
Because it is relatively cheap to process into a wide variety of uses. Petroleum is everywhere in our lives. Lubricants, fuel for heating, gasoline, it is used in manufacturing virtually everything. Other natural resources don't have a fraction of the extended uses that petroleum products have and it all starts with crude oil.
You mean density less than 1 gram per cubic centimeter. The definition of the SI unit: Density of water is 1000kilograms per cubic, that is 1 gram per cubic centimeter. So, a material with a density less than water means that it swims in water and does not sink.
In contrast, fossil fuels can have a significant impact on water resources: both coal mining and natural gas drilling can pollute sources of drinking water, and all thermal power plants, including those powered by coal, gas, and oil, withdraw and consume water for cooling.
It is a physical change because the oil and the water do not change in chemical composition.
Yes
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.
physical- there's no chemical change.
When oil and water mix it is due to an emulsifier being added to the solution. The emulsifier has one hydrophobic tail which will attach to the oil and one hydrophilic tail which attaches to the water. It is more of a chemical change than a physical one since the oil and water don't change state, however they will not form an emulsification without an aid so its technically not due to a chemical reaction between the water and oil alone either.
No, it is a physical process.
chemical change. the dressing and mayonnaise changed completely to form the sauce.
your mixing two chemicals together so of course its a chemical change
Mixing sand into garden soil is a physical change. This is because the sand's composition remains the same, and it can be separated from the soil by physical means (such as sifting). No new substances are formed during this process.
Oil and water do not mix because they have different polarities. When oil and water are mixed, they separate into distinct layers due to their different densities. This separation is a physical change where the molecules of each substance retain their original properties.
very bad! change the oil
Yes.
