It is a chemical change.
Because combustion (burning) produces substances with new chemical properties, this process results in a chemical change.
exhaust fumes of a car
No who, but what. All internal combustion engines emit exhaust fumes.
Exhaust
The exhaust system is what muffles the engine sound keeps the fumes out of vehicle and away from the vehicles occupants and also filters the exhaust fumes out.
Chemical change because its form is a new state then what it was when it started (:
your exhaust may be jammed
Exhaust
You kids exhaust me! That exhaust fumes from that car are choking me.
They don't. You need to stop sniffing exhaust fumes, mister.
Blue exhaust fumes are an indication of burning oil, which is mixing with the fuel - probably from a leaking piston ring or valve seal. You definitely need to bring your car to a mechanic for a check-up.
Take a second, lightly sniff gasoline fumes before its been burned, then compare with exhaust fumes, and see which you are smelling. Exhaust fumes you'll naturally smell around an idling car. unburned gasoline could be the result of an improperly set carb, mixing the wrong amounts of fuel and air, leaving you with unburned gasoline that is boiled, evaporated, and spit out the exhaust. Too much evaporated gas turns your exhaust black, so ive been told, so there could be a sign.
