NO
You can replace an Intel Core Duo Processor by first removing the heatsink and/or fan from the processor and removing the old thermal paste. Apply thermal paste to the new Intel Core Duo Processor and reseat the heatsink and/or fan.
Before installing your Heatsink and Fan to the processor you should be applying Thermal Paste. There are several hundred versions on the market and any good computer store will have ooddles of the stuff. Ideally don't spend less that €10 on a tube. If its cheaper than €10 its generally useless. In some case, some of the more expensive thermal pastes contain an adhesive to ensure the heatsink sits better on the processor.
There should be no problem placing this processor into an eMachines et1831-05. If everything in your question is provided correctly, the et1831 uses the required motherboard socket, the LGA775. You really should be able to slip it right in and go without any issues whatsoever. Keep in mind you need to apply thermal paste thinly and evenly on your processor before putting the fan back on. Clean the heatsink + fan all around (Including the thermal paste from the previous processor) before applying. other than that, you should be great!
No. They should be good thermal insulators.
The CPU fan and the CPU heatsink (in liquid coolers, this would be the radiator).
Officials should use thermal underwears when they feel the cold.

In a active heatsink system you have both a heatsink and a fan thus for the most part an active heatsink cools better with one exception. Should the fan fail the active heatsink will quickly overheat. Passive heatsinks relay on transferring heat without the aid of a fan. The advantage here is that a passive heatsink is fail proof and uses 0 electricity, however passive heatsinks don't typical cool as well. Passive heatsinks work great for supporting chips and RAM cooling. They are also found in servers because of the no fail aspect. EnzoTech produces some passive heatsinks you can read a bit more about them here: http://electricalninja.com/
There is a certain operating range for each type of processor. As long as you install the proper heatsink and fan, your processor should never overheat. If you plan to overclock your processor, (make it work faster than it's really intended to) then you need to take the necessary steps to keep it cool. Such steps can include adding a bigger heatsink, a faster fan, and/or adding liquid cooled hoses to it.
because it is easy.
Compound adjective is the proper spelling of this phrase.
Thermal power plants release greenhouse gases. They should treat the gases before releasing.
