I have this processor and want to upgrade to Seventh-generation quad-core Intel Core i5 processor.
Is this possible and can I just bring my computer down to Apple to purchase and install?
iMac (20-inch Early 2009), OS X El Capitan (10.11.6)
Apple will not do it for you. Although it is supposedly possible to make the CPU change you must use one with the same pin arrangement as the socket on the motherboard. Then there would be the power increase and cooling demands. Disassembly is not easy and requires both knowledge and skill not to mention instructions (search for them on Google.) If you want the seventh gen. CPU then buy a new Mac. You may get enough money selling your old machine to pay the cost of buying the CPU.
Note that if you take the machine apart and make any unauthorized changes, Apple will not provide you with service should you need it. If you pursue your request be sure you know you are well-qualified to perform the work.

It does appear to be possible. For more details read Can the processor in the 2009 iMac be upgraded?
In addition to what others have said, even if you could upgrade
the CPU, there is no firmware to support it so it would simply not work.
