Why does a car exhaust rust quicker than the car body?
One reason why car exhausts rust faster than the car body of the car is because they are often at a different temperature.
The exhaust can be very hot and very cold so this creates a reaction rate which inturn makes the exhaust rust faster.
hope that helps :)
Water will cause iron and steel to rust ( Oxidise into FeO2 ). Dissimilar metals rust more quickly than pure metals as a result of electrochemical reactions, this is why steel rusts quicker than iron, also joints between dissimilar metals rust very quickly. Salt water will accelerate rusting because salt water is a better electrical conductor. rust is an endothermic reaction, so heat also speeds it.
First of all Nails in salt water rust quicker. That's because salt is sodium chloride and that affects a nail by rusting it. No i did a experiment on which one rust faster. After 5 days the nail in the tap water rusted way faster than the nail in the salt water. With DISTILLED water, the nail will not rust as fast as the salt. TAP water will rust faster then salt.
Well, they don't get cold...........cause they're dead.... However, the body will cool down quicker due to wind chill as the process still strips heat out of the body quicker due to improvement to conductive heat losses. This will make determination of time of death more difficult as the lower the temperature of the body: the slower the body decomposes making it harder to accurately determine the exact time of death (it looks like the body…
