I found a nice video that explains how a CPU works and it seems to get very detailed: See How A CPU Works

This video, while very educational, is mind-blowing - I had no idea a CPU did this much work.

Questions:
1. Is this video accurate?
2. This video implies that a CPU can only handle one operation at a time. So, it's not technically multitasking?
3. As fast as these operations are happening in reality, is this the reason that a CPU gets so hot?
4. Would a CPU be able to double its speed if we found a way to keep it from creating heat?
5. RISC means Reduced Instruction Set Computing. What exactly is "reduced"?

Thank you in advance. I always try to find things like this because I enjoy learning about computers.
