Burning a gas to produce exhaust fumes and other gases is a chemical change. This is because the burning process involves a chemical reaction where the gas molecules are broken down and rearranged to form new molecules, resulting in the release of energy and the formation of new substances.
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.
Exhaust fumes from cars are an example of air pollution. They contain harmful gases and particulate matter that are released into the atmosphere, contributing to environmental and health issues.
your exhaust may be jammed
You kids exhaust me! That exhaust fumes from that car are choking me.
Exhaust
When gasoline gives off fumes, it is a physical change because the substance is still gasoline, but it has changed from a liquid to a gas state without undergoing any chemical reactions.
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.
