I am wondering, when you change the cpu multiplier does the chip get hotter? I mean, if i take my athlon 2000+ and move it to say the equiivalent of 2200+, would it make more heat than a 2200+ would normally?

Yeah, I think so. Because when u OC it , CPU need to run at a "FULL SPEED".

Actually, your CPU runs hotter because your chip was manufactured to work at a certain speed, at which the chip's circuitry is designed to run communications at that speed, though when increasing either the front-side-bus or the multiplyer of that CPU, you're forcing signals to pass through circuits that may not be "optimized" for that speed, and therefore yes, an overclocked PCU can and WILL overheat

Woohoo! Broke the 30-celcius barrier with through the loud and innefficient world of air-cooling! Also, never - NEVER - play with gum in one hand and hair in the other... just trust me.

A 2000+ with nothing but the multiplier changed to make it a 2200+ will make exactly the same amount of heat as a real 2200+, (because that's all a real 2200+ is).

...if its the same core design.

OK, you've heard the two sides, now for something more "in the middle". Every CPU is a little different. Every CPU has manufacturing flaws. These flaws can cause a CPU not to run more than a certain frequency, either because it gets hot or because it simply won't pass a signal through some part fast enough. Now, there are a few reasons why your CPU might have been marked as a 2000+ instead of a 2200+. First reason is, due to a hot spot or whatnot, it exceeded thermal specs at the higher speed. Overclockers overcool to take care of that. Another possibility is that it simply wouldn't pass the signal at a higher frequency through some circuit. Overclockers address this by raising core voltage, which makes more heat. Oh, and the most desireable reason your CPU might have been marked at the lower speed is: They needed more 2000+ CPU's to fill the order. In the last situation, overclocking it would not raise the heat beyond a stock 2200+.
