Upon heating, vegetable oil will first become less viscous (less thick and more runny) as it is heated, and eventually, if heated hot enough it will smoke and then burn.
No, you will severly damage your hair! Vegetable oil is made to intensify heat while cooking, so if anything it helps heat damage your hair.
Olive oil holds heat better than vegetable oil. However, all types of cooking oils are susceptible to heat damage if they are left on a burner for too long.
i wanted to know the effect of the above question on vegetable
Vegetable oil's effect is to allow foods to be cooked like with any other oil. It has a higher smoke point than many other oils, and is quite reasonably priced.
Yes; that is how we fry food.

Yes, it does if the heat is high enough.
No, it would effect the chemistry of the oil.
Definitely NOT vegetable oil because we heat it all the time and it hasn't set on fire.
Vegetable oil
Vegetable oil can be made out of several different plants, including soybean, peanuts, canola, and sunflower. So while all sunflower oil is vegetable oil, not all vegetable oil is sunflower oil.
The oils have very similar compositions as regards specific heats and rates of heat transfer. It would be difficult to measure a difference outside the lab.
