What does it mean when my 1991 Acura Legend Yellow Service Light comes on?
It means that it is time for an oil change. I just found that out. Usually when you get an oil change from a professional place they reset the light for you. If you do the oil change yourself, then you must reset that light yourself. Its easy, under the maintenance required light is a hole, I though it looked like an alarm sensor but I was wrong. That's were you stick your key in the hole and the light changes from Yellow to Red then Green. Green represents, you have complied and the car can go 3000 miles, until the light changes Yellow. Yellow represents (Warning) it is time for an oil change. If you don't change the oil and continue to drive another 1500 miles the light changes from Yellow to Red.Meaning (Danger) now it is def time to change the oil.

Is a leaf changing colors a chemical or physical change?
Leaves change colour because the green pigment (chlorophyll) is degraded, then other pigments like anthocyanins (red or purple) and carotenoids (yellow) are exposed. So the change is more chemical than physical. Leaves going brown are also caused by chemical changes, but it also means the leaf cells are dead or dying.
