Expert Answer:

Yes, rusting is slow combstion.
We know that, combustion is the rapid reaction of substance with oxygen to produce heat.
During rusting, iron reacts very slowly with the atmospheric oxygen to form rust that is iron oxide. It also produces heat but to a very small extent. Hence, as the rust cools off at the same time it is heating up.
Hence, rusting is slow combustion.
