Heating oil before adding mince and onion helps to create a non-stick surface, allowing the ingredients to brown properly and develop flavor. It also ensures that the oil is at the right temperature for cooking, which can help the meat sear quickly and lock in moisture. Additionally, heating the oil allows the onion to start softening and releasing its flavors before the mince is added.
Crude oil is heated at about 350 degrees
Oil does expand when heated and contracts when cooled.
Oil shale is a type of rock that contains kerogen, a precursor to oil. When heated, the kerogen in oil shale can be converted into oil and gas. This process is known as pyrolysis.

To cook mince in a pressure cooker, start by heating a little oil in the pot and sautéing onions, garlic, or any desired vegetables until softened. Add the mince and cook until browned, breaking it apart with a spoon. Then, add your choice of liquids (like broth or water) and seasonings, close the lid, and cook under pressure for about 10 minutes. Once done, allow the pressure to release naturally or use a quick release, and stir before serving.
When oil is heated, the molecules gain energy and move more vigorously. This causes the oil to expand and become less viscous. If it continues to be heated to its smoking point, the molecules can break down and create harmful byproducts.
To enhance the flavor of your dish with a large garlic clove, you can finely mince or crush the garlic before adding it to the dish. This will release more of its flavor. You can also saut the garlic in oil before adding other ingredients to deepen its flavor.
When oil is heated, its volume increases due to thermal expansion. This is because the heat causes the oil molecules to move faster and spread out, leading to an overall increase in volume. Additionally, the expansion of the oil can also be attributed to the decrease in its density as it becomes less dense when heated.
Higher, I suppose.
When oil is heated, its molecules gain energy and move faster, causing the oil to become less viscous and more runny. The increase in temperature decreases the oil's viscosity, making it flow more easily.
No, use heated mineral oil or linseed oil, or a polyurethane sealer.
