Yes, it is compatible.
It depends on the motherboard. If your motherboard supports core i3, it is possible, if not it isn't.
it is 35% faster than Pentium
As long as the motherboard has a compatible expansion slot, yes.

No, you cannot.
The Pentium is a PC chip, or what oldschoolers call "IBM-compatible." i.e, non-Mac.Since the Pentium (and the stuff it attaches to) IS the computer, I'm guessing what you're really asking is, what will the Pentium processor run?It'll run Windows (and keep in mind that there have been Pentium processors since 1995, so you'll want to figure out whichPentium you have before you run out and buy Windows 7.They'll also run Linux (including Ubuntu), Unix, and other OS's - - essentially (again), if it's not the Mac OS, it'll probably run on a PC.
The i3-370M. It simply has a faster clock, that i3 can be clocked at 2.4GHz and the Pentium only 2GHz. I think the Pentium is aimed more at the budget market. I looked at a CPU mark score and the i3 has 2,211 and the P6100 is just 1,566. I also guess that the i3 had better integrated graphics than the P6100 if you're not getting one of those mobile cards like the radeon HD 5650 mobility etc.
Dozens of motherboard models are capable of supporting an Intel Pentium Dual-Core.
Not necessarily. There have been three different sockets used for Pentium 4 processors (Socket 423, Socket 478, and LGA775). They are not interchangeable without special adapters. Even when pin-compatible, motherboard updates may be necessary for the processors to actually work.
This depends on what type of A-Series you are talking about, but the i3 is better than the Pentium Dual Core although they are based on the same microarchitecture.
